Every so often, we receive phone calls from hospitals or medical centers that need to have equipment removed in a big hurry. An MRI or linear accelerator project is usually planned months in advance, but every so often, circumstances require an expeditious removal.
R.O.S. to the rescue.
Recently, a customer in the Cayman Islands needed help in a hurry. A 2007 GE Profile Excite IV MRI System weighing 20,000 lbs., had to be removed in a hurry.
The result? On time, on budget, expeditious, professionally and safely executed, with a happy customer.
Antes de comprar un acelerador lineal de segunda mano, es importante identificar los tipos de tratamientos que ofrecerá a sus pacientes, tanto a corto como a largo plazo. Este gráfico le permite ver qué requisitos de hardware son generalmente necesarios para cada una de las diversas opciones de tratamiento. Hay excepciones a estos parámetros (por ejemplo, algunas instalaciones están haciendo SRS sin tasas de dosis más altas).
Before you purchase a pre-owned linear accelerator system, it is important to identify the types of treatments you will be offering to your patients, both in the short term and in the long term. This chart allows you to see what hardware requirements are generally necessary for each of the various treatment options. There are exceptions to these parameters (for example, some facilities are doing SRS without higher dose rates).
Linear accelerators have two different components that allow for images of the patient to be made while the patient is on the linear accelerator:
1. MV Imaging Devices. These devices, also referred to as EPIDs (Electronic Portal Imaging Devices), produce an image of the patient by the use of the mega voltage (MV) beam of radiation that the linear accelerator emits to treat the tumor(s).
2. KV Imaging Devices. These devices produce clearer, x-ray images of the patient through the use of an x-ray tube that is mounted onto the linear accelerator.
Linear accelerators have become increasingly more sophisticated over the last two decades. The advent of IMRT (intensity modulated radiation therapy), as well as CBCT (cone beam CT) and VMAT (volumetric arc therapy) means that more data is generated from the linear accelerator than ever before.
In order to keep all of the patient data organized, a Record and Verify System (R&V) should be used. An R&V system is simply a computer server and related software that organizes and stores all of the data that is fed into, or captured from, the linear accelerator and the related patient being treated.
Today proton therapy is more popular than ever before. Most major population hubs in the U.S. either have a proton center, are building one, or are thinking about building one. Choosing the right patient positioning laser system to use in a proton therapy center is key to delivering the most accurate and precise treatment possible.
Our recent Refurbished Medical Equipment Survey results indicate a trend that we have been seeing for some time now. More and more hospitals and clinics in the United States are opting to trade in their used equipment to OEMs (original equipment manufacturers), rather than selling them outright in the open market.
Let’s face it. For many hospitals, trading in equipment is a much easier process than selling or consigning a machine. Just like trading in a car when you buy or lease a new one, you let the Seller take care of the headaches. After all, isn’t one transaction a lot easier than two? Selling equipment often involves dealing with multiple buyers, the headaches of not knowing the professionalism and reputation of each, and that can put you and your facility at risk. So why deal with all the hassle?
Is your facility considering selling or replacing diagnostic imaging or radiation therapy equipment? There are several options to choose from. We have highlighted the “pros” and “cons” of each.
The Project Management Team at Radiology Oncology Systems (known as R.O.S. for short) recently completed a major project involving installation of a refurbished Elekta Synergy linear accelerator system at a major public institution in Australia. Such an installation generally takes between eight to twelve weeks. In this case, ROS’s team provided an “expedited installation” and completed the work in just under four weeks.
Tommy Hughes, Sr. Manager, Field Operations at ROS, stated, “we received full acceptance to OEM standards by the facility’s physics & medical staff in under four weeks—this is a record for our company, and a big accomplishment for our team”.
In 2013, a survey was conducted among medical physicists and published on the Global Medical Physics list server. The survey asked physicists which higher photon energy is preferred, primarily between 10MV, 12MV, 15MV and 18MV.
All linear accelerators manufactured today include the 6MV photon energy, which is the most widely used energy for performing IMRT. However, higher photon energy options exist, and the selection can often be confusing.
Who better to ask than the medical physics community? The results, we found, were surprising. Given the choice to alter the energy pairs on their linear accelerators, physicists chose 10MV as the preferred second energy.
