A radiation therapy system and method, especially for brachytherapy, monitors and verifies dose delivered at a plurality of points at or near the region to be irradiated, integrating verification with radiation delivery. In one procedure, mapping is used to determine the shape and location of the region to be irradiated. A treatment plan is developed using the mapping information and a dose prescription. As radiation is delivered to the target region internally (56), the dose received at plural points is monitored (58) and continually fed to a central processor (60). As needed based on feedback (62), the system modifies the treatment plan and delivery of radiation accordingly (64, 66, 68), to arrive substantially at the prescribed dose at all locations in the region. |
