Solutions for Cooling Systems of a LINAC

Posted on by Creative Programs and Systems

LINACs are a type of particle accelerator that increases the kinetic energy of a particle that can be used in a variety of different areas such as scientific research or during radiation therapy to remove cancer cells of a patient. As with most medical and lab-related equipment, particle accelerators are negatively affected by thermal changes, especially with an increase of heat. It is of most importance to maintain temperature control of the equipment components to guarantee the integrity, performance, and reliability of the system. A solution that helps maintain temperature control is using a custom liquid cooling system. We will further discuss this option below so you can adequately care for your LINAC equipment.

How A LINAC Works

A medical linear accelerator (LINAC) produces and delivers a radiation beam using high energy x-rays or electrons to a targeted area to destroy cancer cells while carefully not damaging the surrounding normal and healthy tissues nearby. The medical equipment accelerates electrons in part of the accelerator called the waveguide and then allows the electrons to collide with a heavy metal target to create the high-energy x-rays. The radiation beams are shaped as they exit the machine to conform to the shape of the patient’s tumor. The patient lies on a movable treatment couch and the lasers are designed to be sure that the patient is in the correct position. The couch can move in a variety of directions along with the gantry – the part of the accelerator in which the radiation beam comes from.

Cooling System Needs

When using a LINAC during IMRT (intensity-modulated radiation therapy), the thermal consistency is necessary to maintain beam energy and stability. All the parts inside the equipment such as the tungsten target, waveguide, acceleration chamber, and the magnets need accurate thermal control to eliminate heat buildup and to allow the temperatures to remain the same for optimal usage for operation. Some of the parts within the machine, like the waveguide and filament material, require temperatures within .5 degrees Celsius. The solution to this is to install a liquid cooling system as the best option. In an IMRT system, the cooling path can be complicated. The water starts by cooling the charging drawer and oil pump. It then leads to the liquid cooling system that will decrease the temperature of the entire system, including the linear accelerator.

Types of Liquid Cooling

Liquid cooling systems are ideal for temperature control and stabilizing. They are designed to remove large amounts of heat that is generated in a densely packed electronic environment of a linear accelerator. It may cause concern that liquid coolant is so near all these electrical products but if the cooling system is designed and assembled correctly, there should be no issues. A few reasons these systems are more beneficial opposed to air-based heat exchangers is the ability to provide faster cooling, runs more quietly, and is more reliable with less downtime. Three options for cooling systems are:

  1. Liquid – Air Heat Transfer Configuration – a high-pressure pump that recirculates the liquid coolant and an air heat exchanger to remove heat in the liquid system
  2. Liquid – Liquid Configuration – the pump recirculates the coolant and the facility water is used for a liquid heat exchanger to remove heat from the higher temperature side
  3. Compressor – Based Chiller System – the pump recirculates coolant that is chilled to well below standard temperature

Purchasing a CT Simulator and X-Ray Tubes

Posted on by Creative Programs and Systems

Before a patient begins treatment with radiotherapy, a team of experts will meet to develop a specific plan for each individual patient. The first step in the planning process may involve the use of a CT simulator, which includes a CT scan of the area of the body that needs radiation treatment. This piece of equipment is essential during the initial planning process and is a great asset to any clinic or organization to have available for use. Many considerations should be made when purchasing radiotherapy equipment such as a CT simulator, the software and cooling systems, and the purchase of an x-ray tube.

Choosing a CT Simulator Based on the X-Ray Tube

The most expensive component of a CT Simulator that also needs to be replaced the most is the x-ray tube. The x-ray tube is required to endure very high heat loads, preferably having the ability to store 5 million heat units (MHU) or more. The use of high heat unit tubes provides a longer life of the unit, which will, in turn, save on downtime when needing to be replaced. In choosing a CT Simulator to purchase, it is best to base the decision on the tube it comes with. A system that may be less costly upfront may have a tube that does not last very long and could ultimately cost more in the long run than if initially purchased with a better tube, to begin with.

Best X-Ray Tubes for Your Buck

When looking at CT Simulators for purchase, the tubes as explained above are important to consider in longevity. Each system comes with a specific tube and no upgrade options are available. Some of the most popular x-ray tubes for CT Simulation include:

  • GE RT 4 MCS7079 Varian Mini Hercules 7.5 HUU – This tube is well known for not being the best, but perhaps one of the worst-performing tubes with a short life span as well. Another downfall is that Dunlee replacement tubes are not offered for this model and must have a Varian tube from GE that can cost roughly $200,000 new. There are used options for replacements for under $100,000. Overall, this tube should come with a large caution sign showing the many reviews from users to stay away from this system if possible.
  • GE RT 16 Hercules MX240 8.0 MHU – These next tubes have a reasonable life expectancy of about 6,000 to 10,000 patient scans performed however, they have been known to exceed this amount and go beyond 15,000 scans. The tubes are warranted from GE and Dunlee for 6,000 scans. There are new replacement options from the Dunlee manufacturer and Reevo 240G that are priced at $195,000 new. They can be purchased used for $75,000- $100,000 as well. 
  • Philips MRC 600 8.0 MHU – This third option is by far the best in value with tubes that are among the longest-lasting on the market. The x-ray tubes exceed 800,000 to 1,6000,000 scan seconds or roughly 4 to 7 years at a mid-range patient occupancy level. On average, they can cost $140,000 new and $40,000-70,000 used.

Weighing Pros and Cons

Purchasing equipment for radiotherapy is never an easy task with having so many options available, both new and used provided as well. When choosing tubes at a lower price point, it may give a company good value in the short-term, but keep in mind, it will need to be replaced more frequently. If you don’t want to worry about needing to replace the tubes as often, a higher-end tube is your best option, but it will cost more. Ultimately, you need to take into consideration your facilities’ unique needs for the best solution available.

Mysterious Water Leakage

Posted on by Creative Programs and Systems

A peculiar instance of water testing is scheduled for this Friday on mysterious green-colored water that oozed out onto eastbound Interstate 696 in Madison Heights a week earlier. According to this Detroit News article, the groundwater is believed to be contaminated with hexavalent chromium, which produces the green color that had onlookers scratching their heads. Due to the potential danger of this contamination, especially the possibility of local rivers and lake contamination, action is being taken immediately to remedy this situation to keep nearby residents safe. The origin of the water is believed to be from the Electro-Plating Services plant located nearby, which incidentally would not be the first time the plant has been in the news for water-related incidents. Results of the testing are scheduled to be released on Friday.

Australian Milestone

Posted on by Creative Programs and Systems

A big milestone in Australia as Elekta announces the first Australian-dwelling patient treated with its Unity MR-Linac system. In this Yahoo Finance article, the Unity MR-Linac is described as a magnetic resonance radiation therapy system that enables personalized precision radiation therapy through real-time visualization of the tumor during treatment. The patient was at a state in the cancer’s life where treatment wouldn’t normally be possible but was able to undergo drastic improvements thanks to the Linac’s precision and ability to pinpoint tumor spots while avoiding damaging healthy tissue surrounding it. The use of this method will undoubtedly open doors for more Australian patients to undergo treatment with this new and exciting medical technology.

Choosing the Right Finish for Your Pool

Posted on by Creative Programs and Systems


When installing a pool there are many options that need to be considered to give homeowners that picturesque view they dream about when coming home every day for relaxation and leisure. One of the many choices that need to be made is the type and style of finish the pool will have; whether it’s made of plaster, tile, or aggregate. Each finish has a variety of materials, colors, and textures to choose from. The options seem endless; which is the best to use and in what combination? If you’re renovating or installing a new inground pool it’s important to select the best finish that compliments your design and vision. Below, we’ll discuss the different types of finishes so you can find an option that fits your budget and your pool needs perfectly.

Plaster

Plaster is the most common material used for pool surface finishing. It is made from a mixture of water, Portland cement, and either silica sand or marble dust. Many choose a traditional white plaster, also known as marcite, which gives the pool a clean, smooth appearance.  An available option with plaster is to mix color pigments or dyes to give the pool finish more depth and create a unique appearance. The color that is most popularly added is medium grey because it gives the pool water an amazing blue tint that many are looking for. Darker colors like dark grey and black are used to create more depth or to appear like a natural lake or pond. Plaster finished pools remain the least expensive pool finish and generally lasts 5 to 7 years before signs of repair are needed.

Aggregates

The newest form of pool plaster surfaces is called aggregates. They are a combination of white or colored plasters mixed with little pieces of stones such as quartz, granite, or glass beads. Aggregate finishes are growing in popularity due to its resistance to chemicals and staining compared to standard plaster and it also extends the life of the finish by 12 to 20 years. Since there is a beautiful variety of colors and textures to mix together, every finished pool has a one-of-a-kind look that many people are after making this another great choice.

When choosing aggregates, you’ll need to decide if you want the stones polished or exposed. A polished aggregate finish has crushed colored stones that are applied by hand to the pool shell by a professional plaster company. It is then polished to show the stone’s luster more clearly and makes the surface smooth. Exposed aggregates contain small river pebbles or glass beads that are also hand-applied. After application and while still wet, the exposed aggregates are power washed using a mixture of muriatic acid which removes the top layer of concrete exposing the colored pebbles or glass beads. This style has a rough texture to create traction to the pool surface.

Tile Finishes

If your looking for one of the most durable finishes with endless design options, look no further than tile. Tiles are typically applied at the waterline of a pool or onto steps to accent the pool, but they can be used to finish the entire interior of the pool as well. The biggest disadvantage in using tile, however, is most definitely the cost and the amount of time required for installation. It may be well worth it in the end though since the life of the tile should never need to be redone, unlike other finishes. Tile can be made from ceramic, porcelain, glass, and even stone which gives a large variety of shapes and colors for a unique appearance.

No matter which finishes you choose, they all offer stunning beauty to your pool in which you’ll enjoy for many years to come. Consult with a professional plaster company to help you decide between the many options available for your pool. Pound Pool Plastering serves both commercial and residential settings and provides all pool-related services to meet your needs including plaster, caulk, tiling, cement decks, and plumbing.

Water Filters 101

Posted on by Creative Programs and Systems


Water is one of the most important elements on this planet and without it, we would only live a few short days. Our bodies are made up of roughly two-thirds of H2O and to keep a healthy balance, we need to consume 2.4 liters of water each day. It comes to no surprise that new ways are constantly being found in order to provide us with more clean, pure water to nourish ourselves. In order to remove many of the harmful impurities from our water, the use of water filters is a solution to this problem. How important are water filters you may ask? Let’s take a closer look at what a water filter is.

How Filters Work

Water filters use two different techniques in the removal of dirt and debris. The first is physical filtration in which water is strained by a physical barrier such as a thin gauze or fine textile membrane to remove the larger particles. The second method is done thorough chemical filtration, which involves water passing through an active material, such as carbon, that removes impurities as they pass through chemically. There are 4 primary methods used for water filters that use a combination of physical and chemical filtration:

Activated Carbon Filters

This type of filter is the most common and popular of the options available that are based on charcoal. Charcoal is a form of Carbon that is very porous because it has a big internal surface area that can trap foreign particles. Larger contaminants are stuck on the outside, thus being removed from the water. Carbon can also act as a magnet for items such as lead and VOCs that continue to remove particles internally as water passes through the filter. On the chemical aspect, chemicals like Chlorine are removed during a chemical reaction when water is in contact with Carbon. The main disadvantage of this type of filter is after time it will get clogged with impurities and need to be replaced, which can add additional costs down the road. 

Reverse Osmosis

Filtration that removes contaminants by water pressure to force tap water through a semipermeable membrane is called Reverse Osmosis. The membrane is an effective, very fine filter that allows the water to pass through but the contaminants like Lead, Mercury, and Iron stay behind. The downside is certain items such as some pesticides, solvents, and metals like Chlorine and Radon can not be removed with Reverse Osmosis.

Distillation

A natural option for filtration can be done with the simple process of steam distillation that involves heating water to boiling and then cooling the steam to remove the contaminants. Most contaminants have a higher boiling point than water which is why they are left behind when the water becomes steam. The steam is collected and transformed back to water in a separate container. The disadvantage to this type of filtration is some contaminants such as volatile organic compounds (VOCs) boil at a lower temperature than water and they evaporate with the steam and can remove beneficial minerals in natural water during the filtration process.

Ion Exchange

This filter is very good at softening hard water by removing limescale. The process is done with chemical filtration method by releasing ions, like sodium, and exchange them for unwanted ions like heavy metals found in your water. The result is better-tasting water, however, the sodium is simply another form of contaminant, so the ion exchange doesn’t exactly make the water “pure”. This option is not the best for people on low-sodium diets. The second disadvantage of ion-exchange filtration is that it will need to recharge the filters occasionally with more sodium ions by adding a certain type of salt.

Why Buying a Refurbished Linac Makes Sense for a Clinic

Posted on by Creative Programs and Systems

When deciding to add or upgrade a facility’s medical linear accelerator (Linac) many factors need to be thoroughly examined such as budget, location, time frames, and other personal impacts. One major decision to make is if to purchase a new or used/refurbished Linac and determining which will offer the best benefits long term. Depending on your situation sometimes a new Linac is required but most often a refurbished option will work perfectly, allowing you to save money as well. Below, are a few reasons to choose a refurbished linear accelerator for your next purchase.

Fewer Patients Being Treated

If your company is new or smaller in size, purchasing a refurbished Linac could be very beneficial. Pre-owned or refurbished Linac’s cost less and have lower monthly lease payments than choosing new equipment. Having fewer than 8 to 10 patients a day is generally considered a small medical facility. With fewer patients equals less money to help cover the costs of equipment fees so taking it low and slow maybe a better business option to guarantee that your clinic continues to grow at a steady pace, allowing quality and effective treatments for all patients. Veterinarian clinics or research facilities may also benefit from a refurbished Linac as they generally do not require all the advanced technologies provided in newer models. The use of linear accelerators may not always be for medical use; instead for industrial uses to image materials.

 Operating with Only One Linac or Want a Backup

Often a dilemma will arise when a company is moving into a new location and cannot afford to have a machine down during the relocation process, which can take about 3 to 4 weeks for the transition. An option to avoid this situation is to purchase a refurbished replacement that is like the existing equipment and have it installed in the new location. Once the new facility is complete and open for business, the patients can receive treatment with the newly refurbished equipment and you can either keep the original linear accelerator as a backup or sell it. This solution prevents companies from losing patients from a lack of available machines.

Other Factors to Consider in Budget

Purchasing a used or new linear accelerator is only the first step in getting the proper equipment setup for your business. Other services that should be researched with your Linac is the warranty, service and maintenance plans. This information will help you decipher which options are best for your facility and meet your needs. Also, remember to consider the costs of equipment removal and disposal. The purchasing and planning process of linacs can be very overwhelming which is why choosing the right company for the job is key for a successful addition/upgrade to your facility.

Bathroom Remodeling Must-Haves

Posted on by Creative Programs and Systems

A bathroom remodel is typically on the top of every homeowner’s dream list of upgrades they would like to accomplish in their homes. Whether the upgrade is for resale value, or for personal enjoyment to have a place to come home and relax in there is a bathroom renovation for everyone. To begin the planning process of a bathroom remodeling project, it is important to have a design in mind along with a realistic budget. Choosing to hire a professional home remodeler is a great option that can help during the planning process to make things run more smoothly. Below are a few helpful tips when doing a bathroom remodel in your home.

Before Calling the Professionals

A bathroom remodel can be very daunting, and many homeowners are eager to call their licensed contractor right away to start the project. Before you pick up that phone to call, you should first begin the initial plan with the members of your home and get a firm grasp as to your needs/ wants for your bathroom. Think of a budget you would like to stay in proximity to and always plan for a little extra because, with any renovations, there is always the possibility of unexpected issues that can arise and will increase costs later. One of the other factors that can change your mind on several details to the project other than money is timing. Be sure to expect any renovation to range from 30-90 days to complete which can be tough since the bathroom is a main room in the house, we use daily for our hygiene needs so having a backup bathroom that will be used or other obstacles will need to be thought thoroughly as well. It is also important no matter how long the renovation is taking to stick to your original plan as best as possible. Even the smallest changes can add extra money and time to the project that will be sure to ass additional frustration.

Designing Your Space

Generally, a home will consist of 1 or more bathrooms in a home with the features of a toilet, sink, and bathtub. There are optional extras such as a separate shower, dual his/her sinks and other luxuries to add into your bathroom floor plans. It is important to keep in mind what the rest of your home layout and design looks like to keep them flowing nicely together especially if it’s a joining bathroom extension to the master bedroom. Sometimes from a design standpoint is not always functional and with a bathroom that will be getting used constantly, you will want it to be designed according to a usability factor since after all the bathroom will need to fit your lifestyle needs. In some cases, if you are considering renovations to your power room bathroom, your design choices will affect your house guests as well since this will be the bathroom that they will use when visiting as well.

Making the Most of Your Dollars

If you are trying to get the best bang for your buck, there are a few ways you can cut corners when designing your bathroom renovations. First, it is highly recommended to keep the new bath’s plumbing fixtures like the existing floor plan so that new pipes/ wiring does not need to be moved can save hundreds of dollars. However, in a situation where the home is very old or outdated, a professional contractor may find that the pipes and wiring may need to be replaced anyway which may be a good time to move them to a new location if purchasing new ones already during the project. If your budget is tight and you are looking to make your room feel larger than it is without expensive expansions, a few tricks can be done for this purpose. Installing pedestal sinks are a great space saver option when choosing counters. Another great option is installing a glass shower door to make the room feel more spacious since a shower curtain will block light making it feel more enclosed. Another visual item to increase the space of the room is choosing a larger mirror for the vanity as well.

Saving Money with The Help Of an Event Planner

Posted on by Creative Programs and Systems

No matter the size of your party you are planning, it is bound to take a fair amount of time and yes sometimes a lot of stress to get to the finish line of a successful event. While in the planning process, it can be very easy to miscalculate time and your budget if not careful. One of the best options to take advantage of maybe hiring an event planner to help work all the details out more smoothly. The first thought many people have when the idea is brought up is they can’t afford one, but what if I told you, hiring the event planning company can actually save you money in the long run. Below we will discuss how this is possible and will make you change your mind for your next party planning.

Area of Expertise

As with other professions, event planners are specialized in their field of work and are experts in all event needs. Sure, many of us have attended weddings or company work parties and think that they should be able to figure out how to host one as well but sometimes there are a lot more details to the planning portion than one initially realizes. Event planners are familiar with the area, they may be able to recommend out of the box venue ideas that you may not have ever considered on your own. Catering services are also another large detail to decide on and not only with an event planner know the types of food they offer, but also the pricing so that they are sure to keep you in the budget you are aiming for.

Cutting Costs When Possible

As described above, Event planners are more aware of what items costs which dollar amounts more easily than regular consumers. Working with a set budget can be very difficult from the beginning and knowing which items to splurge on and which items can be neglected a little more. If your party spending becomes out of control, it can make it even more difficult to get back on track. An event planner can work with you and create a list of priorities and give advice as to which elements will make the event more unique and then from there they can help decide if upgrades can be removed in certain areas without making the event anything less than special.

Time Savings

Sometimes money is not always the best savings that you can get, but time is. As the saying goes “time is money” it couldn’t be truer when party planning. Event planning needs a lot of time and energy from the beginning to the end. Juggling your regular job while trying to make phone calls and running to appointments to meet with vendors can be a huge headache and cause a lot of unnecessary stress. Not only will your stress increase, but certain details can get missed or forgotten when so distracted which will cause even more problems down the road.

Event Planning DC provides full event planning, partial event planning, wedding planning, month-of (day-of) event coordination, event styling/design and decorating services throughout DC, Maryland, and Virginia, with access to local and national vendors who may provide additional services suitable for your event and budget.  We pride ourselves on providing only the highest quality event coordination, giving you and your guests the perfect day, no matter what the occasion including exclusive corporate and non-profit events, weddings, Bar & Bat Mitzvahs, community events and milestone celebrations.  More information can be found online at https://www.eventplanningdc.com.

Should I Replace or Upgrade My LINAC System?

Posted on by Creative Programs and Systems

Having a shiny LINAC system in your clinic entitles you to benefits and services other clinics lacking this technology do not. Such a system is imperative when dealing with minute cancer situations and can not only give the medical staff an edge but also give patients a guarantee of quality others cannot. That said, a proper LINAC system is, quite obviously, not a cheap system to not only implement initially but maintain over time. At one point a clinician or technician may decide the time has come to upgrade to what’s best out there, but such a decision is not so black and white. This article should briefly outline why so.

What Do You Have?

When making the decision to upgrade, you have to look at what you have already implemented. What you have may actually be satisfactory despite being old. LINAC systems themselves are as pricy as one may expect but are also modifiable with different parts that make up the whole. Linear accelerators can be classified as defined by their part status. Essentially, your linear accelerator can be classified from older and lacking upgrades, through newer but lacking and older and possessing upgrades, to newer and possessing upgrades. Where your system lies on the spectrum indicates whether or not making upgrades is worth the cost when considering the competency.

What is Your Budget?

Depending on the overall budget and success of your clinic you may find it smarter to simply upgrade certain parts on your older LINAC system. If money is no object you can naturally swap out your system – even if it’s new – for a newer, more modern and up-to-date model. Having an infinite source of funds is most likely not the case for most clinics, so you must take budget into effect and decide if your system is old enough to really warrant a true upgrade. Remember, upgrading certain parts of your system will always be cheaper than an outright replacement, and going with used upgrades is still a viable and more cost-effective option.

Do You Have Time?

When replacing a LINAC system completely, time is of great importance. Upgrading certain parts on a system can take hours and can be done overnight, but swapping out an entire system can take much, much longer. Are you able to survive with such an important machine out of the office for so long? If your system isn’t too old and has competent upgrades, then it can be hard to justify that absence. Any experienced clinician understands his or her own office enough to know whether or not that absence is detrimental to overall clinic success.
