Designed to pinpoint radiation therapy with the precision of magnetic resonance, the GE Optima system was recently introduced at the American Society for Therapeutic Radiation and Oncology (Astro) 53rd annual meeting.
Therapeutic radiation has changed immensely over the past 50 years.
The FDA sent the letters to 93 manufacturers of radiation therapy devices informing them of the agency's efforts to reduce the number of underdoses, overdoses, and "misaligned exposures from therapeutic radiation." The agency has not yet set a date for the workshop.
While CyberKnife is a fairly recent invention, Reilly sees a range of possible procedures that could benefit from its non-invasive, precise delivery of therapeutic radiation. "As more data and clinical experience are gathered, we will find an expanding role for this technology where extreme accuracy can address a number of other issues." The technology is showing great usefulness in brain and head conditions, where half of CyberKnife treatments are focused today.
