Abstract
A system and method for radiation therapy delivery. Known delays are compensated for by applying a compensation factor to the dose at the start of the beam cycle. According to one embodiment of the invention, a dosimetry controller is configured to sense radiation on (RAD ON) and monitor the dose rate at the beginning of the beam cycle. The dosimetry controller then multiplies the dose rate by a compensation factor. Thus, for each beam cycle, the dosimetry controller resolves the magnitude of the lost dose rate data and compensates each segment accordingly.
