What Happened When an X-Ray Tube Failed on a CT Scanner

Lincoln, Nebraska

A clinic in eastern Nebraska recently had its CT Scanner’s x-ray tube fail.  This meant it was unable to simulate its patients prior to radiation therapy, and so it had to outsource this service—something highly inconvenient for both patients and clinicians.

There were two options:  Replace the x-ray tube and spend tens of thousands of dollars on a replacement.  Or instead use that money to upgrade and replace its CT scanner, to a later, faster model.  They chose the latter option and called the R.O.S. team to assist.

The end result:  Out came the older, four-slice CT Scanner.  In came a newer, 16-slice, large bore CT.  The R.O.S. team was on the move, and the clinic was back on its feet and treating patients within two and a half weeks.

The larger bore makes it more convenient for patients to be scanned along with immobilization devices (breast boards require the patient to be imaged at an angle, and hence a large bore is needed).

X-ray tubes, like light bulbs, are designed to last a certain period of time, and after a while, they fail.  Some such tubes can cost significantly more than an entire CT Scanner.  In these cases, the sum of the parts is significantly more than the whole!

R.O.S. prides itself in helping facilities in need. The more time it takes to fix a problem, the more patients that are inconvenienced and unable to receive the treatment they need.  Through expediting these processes, we strive to help doctors better serve their patients and to be a part of the global network of medical professionals helping to save lives every day.


R.O.S. Helps Start New Radiation Oncology Clinic

In what we consider a very exciting project, R.O.S. recently helped start a new cancer center in Pennsylvania. When the doctor in charge decided to take on opening a new clinic, he knew, after completing a previous project with us, that R.O.S. would be up to the challenge of providing the required equipment necessary.  And so, we did.

R.O.S. sold and installed a Varian iX Silhouette with OBI linear accelerator and a Toshiba Aquilion Large Bore CT Simulator.  The package also included patient positioning lasers, a power conditioner, a chiller, Safe CT XR29 (a proprietary dose management solution for CT scanners), and a treatment planning system from Prowess, Inc.

It is always a balancing act for a facility to receive quality and essential equipment without breaking the bank, and R.O.S. is proud to have been able to help this clinic start providing life saving radiation therapy while staying under their budget. In fact, we were able to outfit this facility with all the equipment they needed, for a fraction of the cost of brand new equipment.

The lower costs of quality, pre-owned equipment allows cancer treatment centers and diagnostic imaging centers to be able to operate with fewer patients.  This allows more centers to be built in rural areas, making it highly convenient for patients that live there.  Especially for radiation therapy treatments, that require patients to drive to the center and back every day for five to six weeks.

Now, patients in this community can spare themselves the drive to larger cities and hospitals for their cancer treatment and know that they are receiving the best quality care. We’re committed to helping doctors and clinics like this help more patients. 

Cancer Patients in Bolivia Now Have More Access to Radiation Therapy

Varian 6EX - Bolivia

What happens to pre-owned Linear Accelerators?

In one week, a new radiation oncology clinic in Bolivia will begin using its new linear accelerator (Varian 6EX) to treat cancer patients, giving millions of people in need access to modern and lifesaving technology. This clinic is only one of six in the entire nation of 11 million people, and it will begin operations due to its partnership with R.O.S.!

Bolivia is a country in desperate need of better and more widespread cancer treatment.  In a comprehensive study of cancer in Latin America done by The Economist, Bolivia scored the lowest on their Cancer Control scorecard (which serves as a metric of comparison regarding the control and access to cancer treatment). The country scored a 7 out of 30. In fact, access to cancer treatment is so poor in Bolivia, that the IAEA (International Atomic Energy Association), has instituted an official project to improve Bolivian cancer treatment and prevention efforts.

Now, there is one more clinic, one more point of access for the people of Bolivia to receive the treatment they need to live healthier and longer lives. R.O.S. is extremely proud to have been able to help make a difference for the Bolivian people and humanity at large, through the sale and installation of the Varian Linear Accelerator.

The physician who started this new clinic previously worked with the only linear accelerator in his area and saw the immediate need for increased availability of radiology oncology treatments. In deciding to break off on his own and start a new facility, he knew he needed someone he could trust, with similar values, by his side. That’s how he knew R.O.S. was the right group to contact. He knew we have a mission to provide lifesaving cancer treatment to those who have little access to it. He knew that we would care about this project just as much as he did.

We sincerely hope that this device will serve as a stepping stone towards better and more widespread care in this nation with desperate demand for it. With more resources in their native country, more doctors will likely return home to practice medicine, rather than need to seek employment elsewhere in the world, and we hope that this catalyzes change in the quality of medical care available for Bolivians.

Here’s to better cancer treatment for all and a more cancer free world!

R.O.S. would like to thank the dozens of hospitals and clinics in the U.S., Canada, Europe and Australia that chose to recycle their pre-owned equipment, by working with companies like ours.

Elekta Synergy Linear Accelerator Installed

Sydney, Australia

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.

Jason Feder, Sr. Project Manager 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”.

The Elekta linear accelerator was removed from clinical operation from a hospital in the United States.  Acquiring good quality, second-hand machines is one of the principle tasks at ROS.  ROS’s acquisition team, spearheaded by Ed Brown and Jared Coates, looks for equipment that can be repurposed all over the world.  “We have to stay on top of every opportunity to acquire good machines, as competition for good, pre-owned equipment is fierce” added Tommy Hughes, a member of that team.

For this particular project, the ROS-provided refurbished Elekta Synergy Linear Accelerator System boasts impressive features including a KV Imaging System (XVI), iView GT Portal Imager (MV), Intensity-modulated radiation therapy (IMRT), and CBCT (Cone Beam CT).  Patient-positioning lasers and patient monitoring accessories were included in the installation. This well-appointed machine will allow its new ownder phenomenal capabilities for years to come.

Relocating radiotherapy equipment internationally adds another layer of complexity.  A domestic relocation of a linear accelerator is complicated enough.  Dealing with and planning for the logistics of international projects is an additional element that the ROS Team prides itself with. ROS has close to two full decades of experience dealing with such complexities.  Without cutting corners, ROS is able to navigate through importation and customs and move systems half way around the world and have successful outcomes at the other end.

Varian 21EX Linear Accelerator De-Installation & Removal

Zurich, Switzerland

Recently, a facility in north-central Switzerland reached out to ROS for help, we were happy to assist. The Swiss facility had purchased a Varian TrueBeam radiotherapy treatment machine and needed to have their existing Linear Accelerator removed – a Varian 21EX Linear Accelerator, which weighs roughly 21,000 pounds (around 9,600 kg). The facility had upgraded the machine to the newer iX model with OBI (on-board imaging) and RapidArc. This newer technology did not dramatically change the weight of the machine, but it did pose some logistical problems later on.

There was a lot of work to do before the machine could be de-installed.

The Logistics

Prior to removing the machine, R.O.S. first got authorization and approval from the Swiss government for the de-installation. Second, R.O.S. needed to get approvals from its client in the Dominican Republic, where the de-installed Varian linac would be. This necessitated having the linac inspected by an inspector from the Dominican Republic. As one can imagine, there were already three languages involved in the discussions so far but something that can become challenging with all of the technical terminology being used throughout the project.

Once the authorizations and inspections were completed, the next step involved logistics. The facility was only accessible for the de-installation on a weekend. (It is common for businesses in many European countries to be closed on weekends.) However, a weekend project in Switzerland now presented additional requirements: a special permit is needed to use freight trucks on a weekend, and another special permit is needed to use a crane on a weekend.

Now a fourth country enters the story. R.O.S. was working with a German rigging company to move the Linear Accelerator using its shipping frames. EU regulations required the frames to be shipped directly to the facility rather than brought with the riggers. So if the frames were delayed, the project’s small window could expire. A further complication occurred when the riggers were delayed at the German/Swiss border, but thankfully they got there in time, as did our frames.

After a final inspection, it was only a small matter to visit Coop Cooperative (a large Swiss retailer) to pick up the last few supplies needed to finish the de-installation and move the equipment to the crating facility. Now another deadline was looming: the crating facility was only open for a two-hour window on Saturday afternoons.

With no time to spare, the Linear Accelerator system was loaded and off to the crating facility.

From Europe to Latin America

Crating a radiotherapy machine for international shipment requires special care and materials.  The wood used must be heat-treated and ISPM-15 approved (the ISPM-15 measures are to prevent accidental transport of disease and insects from one country to another). R.O.S. also needed special crating for the KV-Imaging Device and the Portal Imaging devices, important components of the Varian Linear Accelerator. Such highly specialized equipment could easily become damaged on the long journey across the Atlantic. R.O.S. crossed these last few hurdles for the de-installation project and the upcoming shipment to the Dominican Republic. Working across cultures and language barriers, and working within each country’s regulations, takes an experienced vendor.

New Radiation Therapy with RapidArc® Delivery

Nebraska, USA

Radiology Oncology Consultants announced that it has installed a linear accelerator system for cancer treatment.  This new radiation therapy machine allows some of the most advanced cancer treatment technology available today.  Radiation therapy is used to treat over 50% of all cancer cases in the United States, and this new machine manufactured by Varian Medical Systems has “On-Board Imaging” and RapidArc®, two cutting-edge technologies that will allow Radiology Oncology Consultants to treat patients with unprecedented speed and accuracy.

“We are thrilled to have a machine capable of RapidArc® delivery available to treat our patients,” stated Dr. P.R. Hynes.  “This treatment technology delivers the prescribed dose of radiation to patients faster than ever before.  The result is a more powerful treatment of radiation with greater patient comfort.  Some treatments can be done is as little as three minutes”.

The equipment was supplied by Radiology Oncology Systems, Inc. of California.  The project took several months to plan and the 25,000 lb. machine itself took over a month to install.  The machine rests under a large steel structure referred to as a base frame, under the floor of the room, to support its weight.  The room is shielded for radiation andvarious underground conduits carry dozens of feet of cabling.  “It’s quite an endeavor to install one of these machines” stated Erin Kruse, Facility Director, “and we are thrilled that our project was seamless.”

James Madison University Project

When James Madison University (“JMU”) of Virginia contacted R.O.S., we were excited.  After all, two R.O.S. associates are graduates of JMU--Michael Teague and Ashley Saunders. 

JMU received a linear accelerator and two conventional simulators as a gift from a local clinic.  They needed a radiation oncology equipment company to perform an evaluation of the donated equipment to determine its viability for continued use, and asked if we could help.  The project involved (1) assessing the current state of the equipment and (2) later relocating it to a repurposed building housing physics research.

ROS rigged out & removed the older equipment first, and then revived the Siemens Linear Accelerator and Nucletron Simulator to the point of patient-ready use.  JMU’s physics department is eager to use the equipment for advanced research projects, and R.O.S.’s associates are happy to have supported their alma mater in a professional capacity.

This Open MRI model was then stored for a few months before being installed in a Fort Worth, TX, facility in August. This project represented a turnkey project in which R.O.S. oversaw the purchase and deinstallation of the used MRI, as well as its subsequent storage, sale to a new facility, refurbishment and installation.

The Airis Elite 0.3T is an Open MRI model, which means it is built to accommodate a larger range of body types, as well as to be more comfortable for claustrophobic patients. This model also offers "fat separation" technology, which provides more image clarity by separating fat from other tissue.

Accuray Cyberknife Removal

Accuray CyberKnife systems have recently come onto the secondary market. These expensive, sophisticated devices are considered “cutting edge” in the fight against cancer, as they target very small tumors in very sensitive areas, like the brain. The CyberKnife competes with other advanced systems like the Elekta Gamma Knife and the Varian Edge. ROS removed this particular device from a cancer hospital in the U.S. in December 2014.

Linear Accelerator for a Cancer Hospital in Peru

A radiation oncology facility in Peru seeking to replace an older and failing linear accelerator decided to replace it with a relatively newer and more reliable system. Reimbursement rates in Peru make the purchase of a brand new system ineffective, so R.O.S. was able to provide affordable equipment to suit their needs. The machine was installed underground, in the basement at the center, which is not uncommon in many locations to minimize the cost of expensive vault shielding by using surrounding earth as shielding. R.O.S. has an extensive network of global resources to perform installations around the globe. The end-result is that patients that otherwise could not receive cancer treatment are able to do so now, in large part due to doctors and clinicians that understand the need to serve their communities, and companies like R.O.S. that can provide cost-effective and reliable equipment solutions. (April 2014)

IMRT and IGRT in Chile

ROS recently installed a refurbished Siemens Oncor linear accelerator with a Theraview IGRT system at a hospital in Chile, South America.  Although Siemens has exited the linear accelerator market, refurbished Siemens machines are still in demand, with hospitals taking advantage of available systems to add, update or expand their existing radiation oncology clinics.  Siemens equipment remains a viable option for cancer hospitals in need of high-quality, low cost equipment. (February, 2013)

Linear Accelerator for a Cancer Hospital in Mexico

The United States has more state-of-the-art medical equipment than any other nation on earth.  Rather than disposing of older/used equipment, ROS specializes in refurbishing it and shipping it to areas where the equipment is badly needed.  Recently, ROS shipped a low-energy Varian 6EX linear accelerator to Mexico, where it will be installed in a cancer center that treats close to 100 patients per day.  We hope this equipment brings care and hope to thousands of patients in the region for years to come. (January, 2013)

CT Simulator Installation at a Regional Cancer Center in the Chicagoland Area.

A radiation oncology clinic in a suburb of Chicago was in need of replacing an older CT Simulator, and didn’t have the budget, or the patient flow, to justify an expensive, new multi-slice large bore system.  With a phone call to ROS, a refurbished Philips AcQSim large-bore CT Simulator became the solution.  The installation of three moveable lasers completed the room, and patients are now being simulated efficiently and effectively in preparation for their treatment. (December, 2012)

New CYRPA Lasers Revolutionize Patient Positioning

Patient positioning lasers are an integral part of the radiation therapy equipment portfolio.  The CYRPA laser company developed an all-new laser system that leapfrogs current market offerings with an exciting new technology.  A level of precision never seen before of 0.1 millimeters.  An auto-calibrating, wireless calibration feature that does the work of the therapist/physicist in a fraction of the time.  And dual-diode red/green lasers to allow the clinician her choice of color. ROS, in collaboration with CYRPA America, is a proud distributor of this exciting new technology.  (October, 2012)

Refurbished Varian 6EX with IMRT Installed in Southern California

ROS is pleased to announce the recent completion of the sale and installation of a Varian Clinac 6EX linear accelerator in Southern, California.  The unit was installed at a newly constructed free standing oncology clinic. The clinic required a cost-effective equipment solution in order to bring cancer care to the local community.  With this equipment the new center is up and running, providing treatment including IMRT technology. In the future, as the practice grows, the clinic will be in a position to add brand new equipment with even more advanced technology. (October, 2012)
