Healthcare Industry News: IGRT
News Release - January 16, 2006
Varian Supplies New Radiotherapy Equipment including 3D Image Guided Tools for Top London HospitalLONDON, Jan. 16 (HSMN NewsFeed) -- One of the UK's leading radiotherapy centers has increased its capacity to offer state-of-the-art cancer combating techniques to patients in London and the south east of England. Two On-Board Imager(TM) devices for 3D Image Guided Radiation Therapy (IGRT) are among the newly-installed Varian Medical Systems equipment at the new University College Hospital in Euston Road.
The UCH is part of a 422 million pounds Sterling, two-phased building project and combines the services of three hospitals including the former Middlesex Hospital, the former UCH and the in-patient facility at the Hospital for Tropical Diseases. Following the recent relocation of the radiotherapy unit from the Middlesex to the new UCH, the department is increasing its treatment machines from four to seven and investing in new technology to keep pace with rapid advancements in radiation therapy capabilities.
Among this increased capacity are four new Varian ClinacŪ linear accelerators, two of them funded by the UK Department of Health and two procured by the UCLH NHS Foundation Trust. The new hospital will equip two of these linear accelerators with Varian's On-Board Imager devices, Cone-beam CT and automated repositioning software, enabling clinicians to carry out treatments using the latest in IGRT imaging technology.
Sarah Hynd, Head of the UCH radiotherapy department, says the robotic On-Board Imager devices will change the way that the team works. "As well as enabling us to improve our ability to image inside the patient and adjust treatments accordingly, they will give us the opportunity to streamline some of our processes and make us more efficient as a department," she said.
She added that a number of cancer consultants at UCH were specialists in their fields and were keen to make use of the better imaging afforded by the On-Board Imager devices for specialist treatments. "As well as reducing side effects and improving outcomes for patients, we intend to demonstrate the benefits of IGRT through participation in numerous research projects and the publishing of scientific papers," she said, adding that a program of intensity modulated radiotherapy (IMRT) would also commence at the new site.
Varian's On-Board Imager makes it possible for clinicians to image and treat on a single machine that rotates around the patient to take X-ray images and deliver treatments from virtually any angle. Mounted on the medical linear accelerator, the On-Board Imager device produces high-resolution images of the tumor and tracks changes in tumor shape, size, or position over a multi-week course of treatment. It also enables clinicians to track and adjust for tumor motion caused by the patient's breathing.
Prior to the advent of IGRT, radiation oncologists had to contend with variations in patient positioning and with respiratory motion by treating a relatively large margin of healthy tissue around the tumor. IGRT enables doctors to minimize the volume of healthy tissue exposed to the treatment beam. Potentially, image data from IGRT tools like the On-Board Imager device will be used to note changes in tumor size and shape over a course of treatment, and make real-time adaptations to the treatment plan.
There are more than 5,800 radiotherapy centers worldwide, and Varian equips 60 percent of these centers with its integrated and automated radiotherapy systems. The two On-Board Imager devices at UCH are only the fourth and fifth installations of their kind in the UK, after Gartnavel Hospital in Glasgow, Clatterbridge Centre for Oncology near Liverpool and Ipswich General Hospital.
