Abstract:
1. A method for intraoperative radiation therapy treatment in a living patient, comprising: following excision of a tumor from a patient, while the patient remains under anesthesia, mapping the excision cavity by the steps of: using a radiation prescription prepared by an attending physician, making a radiation treatment plan for a volume to be treated immediately surrounding the excision cavity based on the three-dimensional model of the cavity, while the patient remains under anesthesia and the applicator remains within the incision cavity, for irradiation of the volume to be treated by use of such ionizing radiation sources and the applicator, and executing the treatment plan by moving the ionizing radiation sources through the peripheral guides of the applicator with appropriate dwell times such that substantially the prescribed dose of radiation is received in all regions of the volume to be treated.
