\n SUNNYVALE, Calif.<\/span>, April 29, 2021<\/span> \/PRNewswire\/ —\u00a0Accuray Incorporated (NASDAQ: ARAY) announced today that Accuray customers took the top two positions in the MArkerless Lung Target Tracking CHallenge (MATCH) experimental branch using the Accuray Synchrony<\/a>\u00a0Lung Tracking with Respiratory Modeling on the Radixact\u00ae<\/sup><\/a>\u00a0next-generation TomoTherapy\u00ae<\/sup><\/a>\u00a0platform, and CyberKnife\u00ae<\/sup> System<\/a>, respectively. The artificial intelligence (AI)-driven Synchrony technology is unique in using image guidance during radiation treatment delivery to detect motion and automatically adapt and synchronize radiation treatment in real-time with the movement of the target.<\/p>\n

The MATCH challenge applied a common measurement methodology to evaluate how closely each participant’s tumor-tracking algorithm was able to follow the position of the phantom target over time. Scoring was based on how accurately and precisely each participant’s radiation therapy system delivered the radiation beam in comparison to the location of the phantom target, based on its pre-specified, programmed motion. <\/p>\n

Accuray customers created treatment plans using the Synchrony markerless lung tracking algorithm on the Radixact and CyberKnife Systems to track targets in the anthropomorphically realistic lung phantom, as the targets moved according to motion traces that closely mimicked real clinical breathing patterns. The results showed that this tumor-tracking methodology is capable of accurately locating lung tumors throughout treatment without implanting any fiducial markers.<\/p>\n

“I’m grateful to have had the opportunity to test our approach for tracking lung tumor motion in the MATCH challenge. The results we achieved mirror those we have seen during the validation of the Synchrony technology on the Radixact System at our hospitals,” said Lee Goddard<\/span>, MPhys, DABR, physicist at Montefiore Health System<\/a>\u00a0and one of the team members involved in the effort. “As part of the process, more than 200 image-guided radiation therapy (IMRT) QA plans were delivered, with the majority being markerless (fiducial-free) lung tumor plans. We precisely tracked targets of various densities and shapes as they moved over the course of treatment delivery, improving the accuracy of radiation doses delivered.”<\/p>\n
