Photoelectron Research Project


Project Summary


The Photonic Radiosurgical System is a unique interstitial radiosurgical device developed by Photoelectron Corporation of Waltham, Massachusetts. This battery powered, miniature x-ray generator is capable of irradiating tissue up to 100 to 200 cGy per minute and has been developed for use in patients with brain metastases. The device is implanted stereotactically into the center of the lesion and then a radiation dose amounting to approximately 1500 cGy is administered over a short period of time. Phase I study of its safety was recently completed in December of 1993 and currently a prospective randomized trial of its efficacy in patients with multiple cerebral metastases is underway.
