IMRIS and Varian developing cancer treatment system with potential to improve
accuracy and effectiveness
ATLANTA, Sept. 26, 2013 /PRNewswire/ -- IMRIS Inc. (NASDAQ: IMRS; TSX: IM) and
Varian Medical Systems (NYSE: VAR) today announced that data presented here
earlier this week at the American Society for Radiation Oncology (ASTRO) Annual
Meeting demonstrates the potential to direct state-of-the-art radiation
treatments using diagnostic-quality MR images at each treatment session.
In a presentation to radiation oncology clinicians from around the globe, David
Jaffray, PhD, a world-renowned radiation physicist at the Princess Margaret
Cancer Centre and Director of the Techna Institute at the University Health
Network (UHN) in Toronto, described a dedicated MR-guided radiation therapy
suite that will allow a magnetic resonance (MR) scanner mounted on ceiling rails
to perform MR-guided brachytherapy and external beam radiation delivery.
Currently being installed at his institution, this unprecedented combination is
a joint development combining IMRIS' MR imaging with Varian's TrueBeam(R) system
for image-guided radiotherapy and radiosurgery.
"Tightly integrating MR imaging with treatment is expected to allow us to
increase the accuracy of radiation delivery and pursue research in the emerging
field of adaptive radiation therapy - the next level of image-guided
radiotherapy that seeks to modify the treatment in response to changes in
patient anatomy," said Jaffray. The team at the Princess Margaret has been
performing research on the use of MR in radiation therapy as well as studying
how the MR and radiation treatment technologies can be made compatible.
"While it is premature to speak to the clinical benefits of the development," he
added, "the technical advantage of enhanced visualization of the tumor and
normal tissues at the time of treatment opens many possibilities." The Princess
Margaret team is planning to explore the system's use in the treatment of
prostate, gynecological, and liver cancers, he said.
IMRIS and Varian are co-developing the MR-guided radiation therapy system that
combines IMRIS's proprietary MR imaging technology with Varian's TrueBeam system
to enable the use of MR imaging during radiotherapy treatments for cancer. The
two companies are collaborating with the team at The Princess Margaret Cancer
Centre and UHN's Techna Institute in Toronto to develop the system, which is not
cleared for sale in any jurisdiction at this time.
IMRIS (NASDAQ: IMRS; TSX: IM) is a global leader in providing image guided
therapy solutions through its VISIUS Surgical Theatre - a revolutionary,
multifunctional surgical environment that provides unmatched intraoperative
vision to clinicians to assist in decision making and enhance precision in
treatment. The multi-room suites incorporate diagnostic quality high-field MR,
CT and angio modalities accessed effortlessly in the operating room setting.
VISIUS Surgical Theatres serve the neurosurgical, spinal, cardiovascular and
cerebrovascular markets and have been selected by 54 leading medical
institutions around the world.
