New Treatment Techniques for XKnife Radiosurgery Presented

July 30, 2007 - Users of Integra Radionics’ XKnife noninvasive radiosurgery presented their latest advances in the treatment of brain, spine and lung tumors at the recent AAPM meeting in Minneapolis, MN.

Dr. Satish Jaywant, associate professor of Radiation Oncology at Robert Wood Johnson University Hospital in New Brunswick, NJ presented his latest work using stereotactic immobilization, cone-beam CT, and the Integra Radionics ImageFusion software algorithms to achieve stereotactic accuracy for extracranial targets. Targets in the cervical, thoracic and lumbar spine, as well as the lung, were treated with the noninvasive XKnife Body Localizer.

Dr. Lu Wang, assistant professor of the Fox Chase Cancer Center in Philadelphia, PA, demonstrated the use of 4-D CT images, taken inside the simulation room, to account for target motion in lung tumors.

Dr. Jimm Grimm from Christiana Care Health Services in Newark,DE, presented a novel method of improving the accuracy of XKnife cranial radiosurgery to 0.2mm on most linear accelerators. Dr. Grimm's SAlinac, a work-in-progress system, uses automatic film test analysis and video registration of laser alignment, together with a wireless hand-held device, which provides real-time realignment advice as necessary.
