Transformative technology featured in 27 abstracts, reflecting growing interest in MR-linac and robust progress of consortium researchers
WASHINGTON, DC, August 5, 2016 – Elekta (EKTA-B.ST) today announced that its high-field MR-linac was featured in 27 abstracts presented at the 58th American Association of Physicists in Medicine (AAPM) Annual Meeting & Exhibition, July 31 - August 4 in Washington, DC.
Elekta’s MR-linac fully integrates three subsystems to achieve unparalleled precision and accuracy in radiotherapy: an advanced linear accelerator, a 1.5 Tesla magnetic resonance imaging (MRI) system and online adaptive workflow software. Combined, these systems allow for simultaneous radiation therapy delivery and high-field MR tumor monitoring, enabling online treatment adaptions in response to changes in the targeted tumor position.
Three abstracts highlight the changing environment during radiotherapy treatment resulting from breathing, digestion and other physiologic activity, and demonstrate how MR-linac can be used to respond to these changes and to ensure accurate dosing of target tissue:
“Establishing online treatment replanning is essential to reduce margins and optimize care for cancer patients,” said Dr. Li. “Image speed and quality are critical to effective replanning, and both require the high-field MR imaging that can be achieved with MR-linac. A growing body of evidence demonstrates that MR-linac supports margin reductions in the prostate and pancreas. Additional forthcoming research from the MR-linac consortium will provide further clinical validation, paving the way to integrate this transformative technology into the treatment paradigms for prostate, pancreatic and a variety of other cancers.”
An additional 24 abstracts were presented during the conference, comprising 15 oral presentations and nine poster presentations. Of these, several describe novel tools, devices and algorithms for assessing and adjusting dose delivery for the MR-linac platform. Findings from these studies indicate that a variety of dosimeters function effectively in the presence of a magnetic field, and that appropriate computer algorithms can be used to adapt additional dosimeters for use with MR-linac. The availability of multiple dosimetry approaches is important for ensuring development of the MR-linac technology in a manner that allows optimized and accurate radiotherapy treatment.
“MR-linac has the potential to fundamentally transform radiotherapy by enabling radiation oncologists to see the treatment target in real time, and to rapidly adjust dosing in response to diagnostic quality MR images,” says Kevin Brown, Elekta’s Global Vice President of Scientific Research. “The data presented at this conference support the use of online adaptive workflow to compensate for intra-session motion, increasing the likelihood that radiation dosing is delivered as planned. We believe that MR-linac is a potentially transformative technology and are encouraged by the significant progress of our consortium researchers and widespread interest in the radiation oncology community.”
Elekta’s MR-linac combines a linear accelerator and an MRI scanner with sophisticated software that allows a physician to see the target tumor in real time. MR-linac is designed to improve targeting of tumor tissue while reducing exposure of normal tissue to radiation beams, which may enable use of higher radiation doses without increased side effects. MR-linac will allow physicians to precisely locate tumors, and to accurately deliver doses of radiation even when tumor tissue is moving during treatment or changes shape, location, or size between treatment sessions.
Elekta’s MR-linac is a work in progress and not available for sale or distribution.
