Abstract
A portal imaging device is used to determine an amount of radiation that is delivered to at least one point while administering a radiation treatment therapy to a patient. Upon detecting that the amount of radiation that is delivered to that at least one point exceeds a predetermined amount of radiation (for example, a planned amount of radiation per the radiation treatment plan), administration of radiation treatment therapy to the patient can be automatically halted.
