Purchasing Quality Medical Equipment

A linear accelerator, LINAC, is a device that accelerates charged particles along a straight linear path of metal tubes at periodic intervals through a process known as electrostatic acceleration. This medical device is used by a radiation oncologist who in addition to consulting with patients and planning treatment sessions, also harness the therapeutic properties of radiation to treat or/and cure cancer using customized high energy x-rays to destroy cancer cells without destroying the rest of the surrounding healthy tissue.

Proper Care Of Your Equipment

Technological advancements have gradually made it easy and painless in curing patients of cancer through radiation that is delivered using a linear accelerator. This is why regular preventive maintenance, quality assurance inspections, installation, testing, calibration, troubleshooting, repair and general maintenance of a LINAC is very important to ensure that the radiation concentration is even across the beam and that the device is in good working order at all times.

It takes time and extensive research, a healthy budget, planning, an understanding of your clinical goals and a commitment to quality care when planning to buy a linear accelerator that will provide patients with quality, timely and uninterrupted treatment options. Additional LINAC system costs and services will also include the following:

• Warranty, service, and maintenance
• 24/7 repair solutions tailored to your equipment needs
• Redundant engineering solutions when the main engineer is not available
• Around the clock rapid response computer-aided dispatching system
• Machine uptime guarantee that ensures that there are no downtimes
• On-demand parts and fast replacement of defective components for linear accelerators
• Proper equipment removal and disposal
• Relocation services of an existing linear accelerator
• LINAC system costs will also include a keen project planning and logistics support
• Power conditioners and patient positioning

Variation In Costs

There are a variety of linear accelerator systems to choose from and in addition to being budget conscious and selecting the right machine, LINAC system costs will also largely depend on the upgrades and features of each system, country of installation, adequate site planning, timeline, pre and post-installation equipment support.

A pre-owned linear accelerator such as a Basic Varian 600CD/6EX can be purchased for around $175,000 to $300,000. However, if you want a LINAC with newer systems such as the Varian TrueBeam, Elekta Versa HD, or the Cyberknife VSI and M6 prepare a healthy budget of around $750,000 to $1.5M. When you want to get the most from your existing equipment is also important to bear in mind other LINAC system costs for its accessories such as positioning lasers, treatment couch upgrades, water chillers, power conditioners, to mention a few.

Additional LINAC Services That Are Offered

There are also recognized professionals that offer LINAC services such as equipment assessments and appraisals for a fee to oncologists who are either looking to expand or close down their clinics, who want to secure funding from lenders, those that need to consolidate their debts, for insurance purposes, or simply to sell their equipment. These are just a few of the LINAC system costs that those in radiation therapy and diagnostic imaging line of work should consider.

All you need to know about LINAC System

What is a LINAC System?

A LINAC system delivers high intensity radiations in the body of patients who suffer from cancer for their treatment. Radiation enters the patient’s body in a precise manner to treat deep-seated tumors. The reason this form of treatment has become popular is because it lessens the overall treatment duration and can more easily pin-point the exact tumor without ruining the surrounding healthy tissue.

LINAC devices, otherwise known as linear accelerators, work by using microwave technology. High energy x-rays are produced by this device by accelerating electrons. When these x-rays exit the machine, they take the shape of the tumor in the patient’s body. A beam is used to direct these x-rays to the tumor. It comes out of gantry; a part of the accelerator.

Factors to Consider for Buying this Machine

If you want to buy such a machine for your hospital, there are certain factors that you need to consider taking the final decision. The topmost factor you need to consider is LINAC system costs. In the recent years, the costs have increased. The clinic needs to have a plan before taking the decision of buying this machine for the treatment of cancer patients.

Moreover, hospital staff and technicians must be made aware of how this system works. Proper training is required for operating this machine. A patient, with a deep-seated tumor, is made to lie on a moveable couch specifically used for treatment purposes. This couch can move in different directions. To ensure that the patient lies in a proper position, lasers are used. Gantry is rotated to deliver radiations in the patient’s body from different angles.

Maintenance of LINAC System

It is important to keep your LINAC machine in a proper condition for its smooth functioning. For this purpose, you will need to contact LINAC services provider for its maintenance. With a little research, you can find a LINAC services provider easily. However, you need to be sure of the standard of their services. Make sure they have experience of handling such a machine and their technicians are expert in providing maintenance services.

Safety of Patients and Technicians

It is important to observe patient’s safety before using this treatment method to cure them. First, the dosage of treatment is double-checked and ensured it is as prescribed by the oncologist. A whole treatment plan is devised for patient keeping in view their condition and place of the tumor. Moreover, every time the patient is to be given a dose of this treatment, it is ensured that the machine is in a good condition and radiation intensity is uniform. Special care is taken so that a higher dose is not given to the patient than prescribed. Apart from patient’s safety, the safety of operating staff is also considered. For this purpose, concrete walls are used to shield the x-ray beams.

Should You Repair or Replace Medical Equipment?

For hospitals and medical equipment owners, the dilemma of whether to repair or replace faulty medical equipment can be a headache. When it comes to oncology equipment components and parts are important to be in top-notch condition so that there is no discrepancy left in treating patients with these important medical devices.

If you are someone who is finding it hard to whether replace or repair the components of your LINAC, then we are here to help you decide.

Take A Look At the History

First, consider the equipment’s past.  According to Healthcare Finance, one of the many things to look for when deciding between repairing and replacing is considering the equipment’s past. Since you have been operating the equipment for long, you should have a good idea of how it had been in the past. Has it had to be repaired, just once in a blue moon or is this first time that it needs to be repaired. If the equipment has needed to be constantly repaired or seems to be failing more and more often than maybe it is time that it is replaced.

Then leverage the costs between repairing the equipment constantly and buying a new machine.  You may find that repairing then equipment costs more than purchasing a new one. This fact holds true especially for the components that have been used for a long time. You should compare the costs of the new equipment and the cost of repairing and then reach a decision.

Also look at the performance of the devices.  Has it been performing well?  Has it been breaking down?  Too often, a broken device does not work properly even after it is repaired. Thus, in this situation, changing it or only the part which had been repaired becomes imperative. You shouldn’t resort to the faulty performance of the instrument just because it costs less.

What do manufacturers say about this?

You shouldn’t replace any equipment just because of a tiny fault for that is going to increase the burden on your pocket. However, when it comes to the following considerations, manufacturers prefer complete replacement.

Innovation in technology is happening every day. There are many parts of LINAC which are improved for better performance. The advance linear accelerators of today have better functionality and reduced breaking frequency. Also, the fact cannot be ignored that some patients prefer to be treated with new and innovative equipment rather than the ones that had been made years ago. Considering this, it becomes important to think about replacing the medical equipment so that treatments are carried out in a better way.

Obtaining peace of mind is an important element for patients and medical facilities.  Evaluating the right price of repairing can be very hard. Before you call a repairer, you should consider how long the equipment would go further in the future after the repair. As you can see this whole process just takes away the peace of mind, replacing the equipment is a better option. Most medical equipment comes with a warranty as you might know. This means that you can expect no burdens of repairing for a long time to come.

Look At Your Finances

If we were to give you a clear-cut verdict on whether you should change or repair your linear accelerator parts or LINAC parts, then we’d say that considering all the factors above, it solely depends upon the state of your company’s finance at the time the machine broke down.

Tесhnісаl Considerations

Thе tесhnоlоgу uѕеd in conventional lіnеаr accelerators is еѕѕеntіаllу the ѕаmе fоr all linear ассеlеrаtоrѕ. Thе hіgh energy generation can bе асhіеvеd еіthеr bу іmрlеmеntіng the "travelling wаvеguіdе technology" оr bу аррlуіng the "ѕtаndіng wаvеguіdе tесhnоlоgу".
