Dr. CR Thomas is shown with a prototype of the Intrabeam intraoperative radiation source, that was delivered to OHSU on November 4th, 2009.
Another first in the Department's effort to bring novel radiatherapy-based technology to the clinical arena, the Intrabeam miniature radiation source emits X-ray beam energies of up to 50kV maximum. A unique feature is that during treatment delivery, an isotropic dose can be applied directly to the tumor bed, sparing healthy tissue and critical structures, hence increasing the overall therapeutic ratio. This adjunct to cancer surgery aims to maximize dose to the target. The high dose rate, low energy X-ray profile requires minimal shielding for personnel in the operating room.
