Abstract
A computer program product, method, system and device that acquires, by a radiation detector, exit radiation measurement information during delivery of patient treatment. Patient anatomy information is also received and a radiation detector response calibration is determined utilizing at least the exit radiation measurement information, the patient anatomy information, and at least a portion of a radiation treatment plan.
Claims16
A system comprising:
- at least one programmable processor;
- and
- a non-transitory machine-readable medium storing instructions which, when executed by the at least one programmable processor, cause the at least one programmable processor to perform operations comprising:
- receiving at least a portion of a radiation treatment plan;
- acquiring, by a radiation detector, exit radiation measurement information during delivery of patient treatment;
- deriving a measured collimator profile from the exit radiation measurement information;
- determining at least one estimated collimator profile from at least a portion of the radiation treatment plan and an approximate image start time and an approximate image end time;
- and
- comparing the measured collimator profile with at least one estimated collimator profile to determine an image start time and an image end time.
