Replacing Equipment: Age Is Not the Only Factor

There are a number of factors that hospitals, medical facilities, and healthcare organizations must consider before they replace equipment besides age. Each year companies could potentially waste thousands of assets by focusing solely on the age of their equipment.

It wasn’t long ago that healthcare facilities were zealous to add all of the latest surgical equipment to their organization. From robotic surgery systems, linear accelerators, and other large scaled medical equipment were installed to keep physicians happy and be competitive.

However, in recent years budgets have gotten smaller and funds have become more restricted and facilities are seeing that equipment can’t just be discarded on a whim or purchased without advanced planning. Instead equipment needs to be repaired or refurbished and kept at peak performance for longer and a strategic approach needs to be taken to replace not only large scaled equipment but also universal equipment such as beds, linens, and so forth.

Proactive replacement planning is necessary between financial and clinical leaders within organizations need to work together to plan in order to achieve:

A reduction in expenses associated with service, parts, maintenance, and training
A decrease “close call” events that come with the use of older equipment with more precise maintenance schedules
A reallocation of assets that are underutilized throughout the facility
An ability to cross train employees throughout facility locations
An increase in consistency and standardization throughout facilities

When the above objectives can be achieved, a reduction in costs can occur with an increase in the quality of care patients receive.

Instead of the reactive strategy that medical facilities have embraced in the past more proactive approaches are being embraced. When purchasing new or refurbished medical equipment in a proactive approach allows leaders to embrace the situation over a period of time verse the reactive approach which tends to be more mission critical. Being proactive allows financial leaders in medical facilities to work with clinical leaders to plan for the addition of new equipment whether it is brand new or refurbished. When the replacement of equipment no longer is a life or death situation a better decision for the facility can be made.

Proactive planning in medical facilities allows for better outcomes overall. Financial teams and clinical teams can work together, armed with historical data, to have meaningful conversations instead of hypothetical ones. This allows better decisions to made for everyone throughout the facility from administrators and physicians to patients and care givers.

Radiation Therapy: Equipment Used by Veterinarians

When many of us think of cancer and how it affects us and the lives we lead we are more often than not picturing human patients however, we are not the only ones that affected by cancer. Today’s post is all about cancer in our pets and how their treatment includes similar treatment plans and medical equipment. Just like in the treatment of cancer within humans, pets use radiation therapy in various forms to shrink and kill tumors.

Radiation therapy delivered to pets can take various forms with the most common form of radiation treatment being delivered via linear accelerators with multi-leaf collimators. The multi-leaf collimator moves while the radiation treatment is on and being delivered to the patient. This allows the radiation therapist to sculpt the treatment around the tumor with very little damage done to cells outside of the area.

Another form of radiation therapy that is used to administer radiation treatment to pets and humans alike is Cyberknife, a linear accelerator that is paired with a robotic arm. This combination allows the machine to move around the patient. The radiation beam is turned off and on and is able to deliver radiation to the tumor from several angles. This ensures that the treatment conforms to the shape of the tumor within your pet.

Treatment can also be delivered through a Tomotherapy machine. A Tomotherapy unit is best described as a mix between a LINAC and CT scanner. It allows an image to be taken of the tumor right before radiation treatment is delivered. The therapist uses the images that are produced to guide radiation treatment to the tumor.

Tumors of the brain are treated with a very specific method of radiation known as the Gamma Knife. The word knife in the name may lead you to believe that cutting is involved however this is not the case. What occurs in Gamma Knife treatment is that very high doses of radiation are delivered to a very specific location on the brain while avoiding normal brain tissue.

As with humans, radiation therapy can be prescribed to pet patients through a variety of methods. One method is known as hyper-fractionated which means that many small doses of radiation are delivered to the pet with the goal being complete eradication of the tumor. This method is most often considered after surgery has been performed when there are small bits of the tumor left behind. Another method is known as hypo-fractionated in which radiation therapists use large doses of radiation in order to treat tumors that cannot be removed through surgery.

A more advanced scheme of delivering radiation treatment are Stereotactic Radiation Therapy, SRT. This includes both SRS, Stereotactic Radiosurgery, and SBRT, Stereotactic Body Radiation Therapy. These methods both deliver high doses of radiation in one, two, or three treatments.

General Radiotherapy Machines

The most common machine used to distribute external beam radiotherapy treatment is known as a linear accelerator or LINAC for short. LINAC systems generate high energy x-rays that are carefully aimed at the cancerous tumors. This process is done with much care given to direct the rays in a manner that does as little harm as possible to the healthy tissue surrounding the tumor. Linear accelerators are used to treat cancerous tumors on all areas of the body.

Some LINAC systems that are more advanced have the capability to deliver radiation on or near the surface of the skin. In this type of treatment electrons are used in replacement of high energy x-rays.

Newer linear accelerators have the ability to deliver radiation using Intensity Modulated Radiation Therapy, IMRT. These systems use multi-leaf collimators adjust the shape of the radiation beam to match the shape of the tumor. Without these adjustments LINAC systems would only be able to shoot radiation beams in the shape of a square or rectangle.

Radiographers all have different methods that they use to make sure the radiation treatment is targeting the exact location of the cancerous tumor. In its most fundamental form radiation is just a plain x-ray. Most linear accelerators work through digital imaging where the bottom arm of the machine takes an EPI, electronic portal image, or PI, portal image.

The image is compared by radiographers, to images that were generated during the planning process of your treatment as a type of checks and balances before treatment is delivered. The quantity of images that are taken to compare between depends on the departments protocol for imaging. Different types of radiotherapy treatment machines have an On-Board Imager, OBI, that is comprised of a Kv x-ray and detector. Higher quality images are obtained as a verification which allows for another radiotherapy technique known as Image Guided Radiotherapy, IGRT. With IGRT the accuracy of treatment is improved as daily changes are accounted for such as changes in organ location which can in turn reduce unpleasant side effects.

Electrons are generated and speed up to almost as close to the speed of light using electrical fields. The energy continues to increase until it collides with its intended target and then releases the photon energy. These photons enter the patient in an attempt to break down the DNA cells in the cancerous tumor. Healthy cells are most often able to mend themselves where as the cancerous tumors don’t and eventually die.

Preventive Maintenance Increases the Lifespan of LINAC Systems

LINAC systems are just one of the methods that facilities use to administer radiotherapy to patients with cancer. The high cost of this technology necessitates that preventive maintenance be routinely undertaken to extend the life span of linear accelerator parts and other radiation oncology equipment. Linear accelerator parts should be serviced to ensure high quality service delivery to patients. This will go a long way in helping cancer patients to access quality treatment.

The main parts of LINAC systems consist of linear accelerator wave guide and the beam defining system. Other parts include: handle control, couch with controls, touch guard and wall panel to hide stand. Being that it is electrical equipment and it’s in continuous use, the systems will breakdown if not cared for properly which will lead to system breakdown. Therefore, preventive maintenance should be regularly done to ensure that the system works effectively and efficiently. A complex system such as linear accelerators and ct scanners depends on electrical connections, once there is poor connection the machine will malfunction. All parts work in cohesion and if one of them is faulty it will affect other parts.

Linear accelerator parts are expensive and the cost of purchasing a new one is prohibitive. Proper preventive maintenance should be carried out from time to time. Most LINAC systems use water cooling because a constant temperature need to be maintained to ensure harmonious operation. However, there is advanced air-cooled chillers for LINAC cooling. This cooling system is expensive but once it is replaced the system works as if it is a new one.

LINAC parts can be procured from the original equipment manufacturer or through local dealers. There are many advantages to buying parts through companies that offer several parts (and services) instead of a more expensive OEM dealer. Often these companies offer less expensive, refurbished options and OEM parts with warranties. If the parts should malfunction within the period of coverage of warranty, they can help. However, one important decision one must make is that whether one should buy refurbished parts or new OEM parts. Refurbished parts are suitable for repairs and maintenance and the cost is lower than buying new ones. This decision is often mostly decided because of your budget however, just know that refurbished parts are just as reliable and as effective so either way you are getting quality parts.

A lot of factors need to be considered when servicing or maintaining LINAC system. One of such considerations is the response time of maintenance company versus original equipment manufacturer. The response time of maintenance companies tend to be quicker than that of the original manufacturer. Therefore, procuring the service of maintenance company will shorten the downtime of the medical equipment. Associated with this is the high level of expertise of engineers working with servicing and maintenance companies.

In most cases, these engineers were trained by original equipment manufacturers hence, the quality of service delivery. Another advantage of servicing and maintenance of linear accelerator parts is that servicing companies have favorable and flexible contract agreement, and this ensure that servicing of equipment is done comprehensively with minimal costs. This contract agreement includes periodical preventive maintenance without extra costs. Routine service and maintenance of LINAC parts are necessary for optimal functioning of the system and it greatly reduces the amount of downtime of the equipment and elongate its lifespan.

Therefore, a little pro-action will go a long way when the inevitable does happen and you need linear accelerator parts or other oncology equipment parts and services.

Proper Maintenance Keeps Medical Systems Running Smoothly

The manufacturer of all medical equipment routinely establishes a regular maintenance schedule that customers need to be able to accomplish in order to ensure that their system is running properly. These maintenance requirements ensure tests are run to ensure that certain linear accelerator parts are all functioning well. The same is true for oncology equipment parts.

Importance of doing regular proper maintenance

When the equipment you are operating is designed for diagnosing a wide range of serious injuries, illnesses, and diseases it is extremely important that they are working optimally at all times. To be sure that all of your machines are properly maintained you should read all of the documentation that comes with each machine and pays close attention to any section that lists regular or scheduled maintenance.

8 Steps Involved in Quality Preventative Maintenance Plans on Medical Equipment

#1 Get the key people in your organization on board with the plan

– In order for any maintenance plan to work you need to be sure that you have all of your people on board with your plan.

#2 Discuss your goals for the plan –

Be sure to discuss all of your goals for the program with everyone to be sure everyone understands them.

#3 Do an initial inventory of all the equipment needing to be maintained –

You should a complete inventory of all of the equipment that will be part of your plan.

#4 Make decisions on the plan you wanting to follow –

Make final decisions on how the plan will be carried out.

#5 Read through all of the equipment manuals –

It is important to know as much about the machinery as you possibly can before you get started.

#6 Schedule long-term maintenance plan –

Set up a long-term maintenance plan that covers all of the vital systems of the equipment.

#7 Schedule short-term maintenance plan –

Set up a short-term plan that covers a more basic look over of the system.

#8 Train your people –

Before you set your plans in motion you want to be sure that all of your people are all on the same page and ready to carry out the mission.

For some medical facilities this type of maintenance on each piece of equipment requires a special department within the organization. For others it is more cost effective to outsource medical equipment maintenance and repairs to a company that specializes in the repair of medical equipment and parts needed for complex repairs on large scaled equipment such as linear accelerators, CT scanners, and a variety of radiation oncology equipment.

When Is It Time to Replace Your LINAC System Instead of Repairing It?

It is a known fact that linear accelerators, LINAC systems are expensive. Not only is the piece of equipment on a whole costly but also buying the replacement parts for linear accelerators can be quite costly, especially if it is a rush order. Hence, regular maintenance and care must be ensured to enhance its lifespan.

The importance of a LINAC system for a healthcare facility provider that offers cancer treatment is known to one and all. This intelligent system is designed to treat cancerous cells and kill them as part of cancer treatment. Therefore, it is considered to be a vital aspect in the treatment of different type of cancers.

Health experts know that the radiation that emits out of LINAC and other such devices also pose certain health hazards. However, linear accelerators boast of advanced safety measures; hence, these machines are programmed to provide only the required dosage that is required keeping in consideration the condition of the patient.

The problem with LINACS, like other systems, they can start to falter over time. Regular use can lead to damages in different parts of the machine, as a result, it may start showing deteriorate signs or stop working completely. A tough decision to make here is whether to get it repaired or if the equipment needs to be replaced.

The key is to know when to fix or when to replace. When equipment starts to falter on a regular basis, it may be time to look into finding a refurbished LINAC system. However, a system that is just experiencing normal wear and tear should be repaired using linear accelerator replacement parts.

You should consider the replacement option in case a part of the system has faltered or stopped working when it starts to occur on a regular basis. However, in a situation where a single part of the system stops, or something occurs that is normal it is a better option to repair the equipment. These large pieces of medical equipment are meant to withstand time so in many cases repair is the best options.

It really comes down to a number of factors such as downtime from the present equipment. If you are continually experiencing equipment failure that leads to cancelled treatments then you may have to analyze the cost between patient care, cancelled appointments, repair expenses, replacement parts, vs the cost of new equipment.

Service Contracts, Procuring Parts, and Timely Repairs

LINAC service contracts are used in hospitals and clinics on medical equipment and machines that are used in the process of treating cancer patients with radiation therapy. LINAC service contracts are agreements between companies that state services will be performed on medical equipment as necessary for a specific time.

Linear accelerators are available in many medical facilities to be used in the treatment of cancer. This machine allows radiation to conform to the size and shapes of tumors in patients with cancer. This treatment is targeted to the cancerous tumors without affecting healthy tissues that are nearby. Radiation oncology equipment is crucial to treatment. This leads most hospitals and facilities to require regular service and maintenance on medical equipment throughout the radiation department.

Many companies servicing LINAC machines have replacement parts in stock and quick access to regularly needed replacement parts; this ensures that important equipment is serviced and repaired in a timely manner to avoid lengthy downtime. The top five replacement parts kept on hand for linear accelerators maintenance and repair include:

Thyratron

It is used as a high power electrical switch and as a controlled rectifier. It is a gas filled tube and it has the capacity to maintain much greater currents than similar hard-vacuum tubes. IT works according to the phenomenon known Townsend in which the gas becomes ionized on electron multiplication. The failure of thyratron can shut the entire system.

Spare Pendant

Another of the important replacement parts of linear accelerators are spare pendants. They are used to control the motions on a linear accelerator machine. Control of linear set for a patient is limited if a spare pendant is not working.

Hydraulic Actuator

A hydraulic actuator is a cylindrical or fluid motor which converts hydraulic power into mechanical energy used to do the mechanical work in the LINAC machine. It can produce linear, rotary or oscillatory motions. It has the capability for high outputs of force and can produce high power per unit of weight and volume measurement.

MLC Motor

The multi- leaf collimator motors are known as MLC motor. These replacement parts of linear accelerators are used to accurately target the tumours in a radiation therapy by shaping the particle beams. They form a vital part in maintaining the capability of a LINAC machine to regulate the dosage of radiation for therapy sessions for different cancer patients. Hence, they are readily stocked to prevent the reduction of LINAC machine’s performance.

Long/Lat drive for patient table

One of the most common but important replacement parts of linear accelerators are the devices used for moving/ driving the patient table in and out of the machine along with side-to-side movement during the therapy sessions. If these devices are not working LINAC machines cannot be operated due to the inability to move patient in the desired position to do the radiation therapy.

Medical repair companies offering service contracts on radiation oncology equipment maintain and keep replacement parts of linear accelerators on hand will prevent you from technical issues created by the last-minute equipment failure. If you need further information about the replacement parts of linear accelerators and from where to procure them feel free to contact us.

The Importance of On-Time Medical Equipment Repair

When you have a business in the medical field, you need to make sure that your equipment is running smoothly. When something breaks, you need to call a repair person quick or else you’ll have to reschedule appointments, which can hurt your bottom line. When your equipment needs new linear accelerator parts, you need a trustworthy repair company that will come out and fix it so that you can go back to running your healthcare clinic.

When you hire the right company, you want to make sure that they come out when they say they will because if they are late or not following the schedule, you’re not only losing money, patient care suffers. Your medical equipment is what makes your practice or clinic money and is imperative for seeing patients. When it’s broken, you need it up and running fast! You have no time to waste because broken medical equipment can take a while to repair, especially if you need to order special linear accelerator parts.

Finding a reliable medical equipment repair company is so important, you might want to look into having some back up refurbished linear accelerators just in case anything happens. This way, you’ll be able to still see patients while your other equipment is being fixed. You won’t have to shut down for the day or reschedule your patients since the refurbished linear accelerators in your office will work just as good as your primary ones.

Refurbished linear accelerators are merely older models that have been refurbished with new linear accelerator parts so that they’re in working condition. In fact, many run smoother than brand new equipment as it has had time for the kinks to be worked out. Having more than one machine in your practice means you won’t be rushed into finding an on-time medical equipment repair company. You won’t have to stress about not being able to accommodate patients and your repair person can take their time figuring out when your primary machine isn’t working properly. Although you ideally want to find an on-time medical equipment company to come out to service your machines, you won’t have as much of a headache knowing that you have a backup refurbished linear accelerator to handle your patient load in the meantime.

Analyzing Linear Accelerators and Their Major Components

Linear accelerators are widely used for the treatment of cancer using high radio-frequency electromagnetic waves to speed up electrons to increased energy in a linear path inside of an accelerator waveguide. The frequency is medical LINACs is around 3 billion Hertz. As the most common form of external beam radiation treatment after a cancer diagnosis it is crucial for end users to have a basic understanding of what a LINAC is. As well as how the major components within LINAC systems work in conjunction with one another to produce radiation treatment.

Consider how a microwave oven works. This is in the most basic sense how a linear accelerator operates. A LINAC uses microwave technology to accelerate charged particles within a waveguide, tube like structure. These electrons then strike a metal target producing photons. It is these photons that are focused on the cancerous tumor. This radiation is delivered in the shape of the tumor to avoid contact with healthy tissues with the use of a variety of positioning devices. Now that we have a general understanding of the linear accelerator lets take a look into the major components that allow LINAC systems to operate as we know them to as of today.

Drive Stand:

A drive stand is a rather large cabinet, usually rectangular in shape, that secures the LINAC machine to the floor of the treatment room that houses the gantry.

Gantry:

The gantry is a moveable frame of the LINAC that is located in the drive stand and rotates on a horizontal axis. It helps direct the photon beams directly into the patient’s tumor. The gantry rotates 360 degrees on its axis. There are three components that are found within the gantry: the electron gun, accelerator structure, and treatment head.

Klystron:

The klystron is a major component that is located within the drive stand that delivers the microwave energy that is used to accelerate the electrons through amplified RF electromagnetic waves.

Accelerator Guide:

The energy from the klystron moves to the accelerator structure to speed up electrons.

Treatment Head:

The treatment head of a LINAC encases the components that shape the radiation to the specific size of the cancerous tumor. This can include: bending magnets, primary collimator, beam flattening filter, wedges, blocks, and compensators.

Cooling System:

The water cooling system in a linear accelerator is located within the drive stand and gantry to regulate the temperature in the space.

In our next installment we will look in greater detail to the treatment head of a LINAC system and the variety of components housed within that help shape radiation beams into the shape of different cancerous tumors.
