METHOD AND SYSTEM FOR USING CHERENKOV RADIATION TO MONITOR BEAM PROFILES AND RADIATION THERAPY
摘要:
A system for providing monitoring of radiation therapy from a source of pulsed high energy radiation disposed to provide a radiation beam to a treatment zone; a camera for imaging Cherenkov light from the treatment zone; apparatus for preventing interference by room lighting by synchronizing the camera to pulses of the radiation beam; and an image processor adapted to determine extent overlap of the beam area from the images. Additionally an image processor adopted to determine cumulative skin dose in the treatment zone from the images. In a particular embodiment, the processor uses a three-dimensional model of a subject to determine a mapping of image intensity in the images of Cherenkov light to radiation intensity in skin of the subject, to apply the mapping to the images of Cherenkov light to verify skin dose delivered, and to accumulate skin dose by summing the maps of skin dose.
