Abstract
A method and an apparatus for dose-guided radiotherapy for a patient (P) having an identified radiotherapy target utilizes a radiation detecting array (R) of radiation-sensitive dosimeters for the real-time remote measurement of radiotherapy at the radiation detecting array (R). The radiation detecting array is positioned within the patient's (P) body along the treatment path before or after the identified radiotherapy target or the device may be positioned beyond the patient (P) to measure transit dose. A radiation source (A) for emitting radiation for radiotherapy along a treatment path through the patient (P) to the identified radiotherapy target is utilized. The method includes generating a predicted dose pattern of radiation at the placed radiation detecting array (R). The predicted dose pattern assumes an on-target radiation source (A) emitting the radiotherapy beam along the treatment path through the patient (P) to the identified radiotherapy target. Gating of the radiation source (A) can occur responsive to the comparing of the predicted dose pattern of radiation to the real-time dose pattern at the radiation detecting array (R). Radiation intensity can vary between low levels to a treatment level responsive to coincidence of the predicted dose pattern of radiation to the real-time dose pattern at the radiation detecting array (R).
