found that the proportion of RET/PTC rearrangements decreased, so the increased incidence of PTC was not due to environmental or therapeutic radiation

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.
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.
Karin Bergmark said, piercing the silence in a symposium at the ESTRO 27 meeting of the European Society for Therapeutic Radiation
Acute effects caused by therapeutic radiation
typically manifest during treatment and resolve a few weeks after completion of therapy.
The ClearPath systems are placed in the patient through a single incision and are designed to conform to the resection cavity, allowing for more conformal therapeutic radiation
dose distribution following lumpectomy compared to other methods of APBI.
