摘要
According to one aspect, a fluence monitoring detector for use with a multileaf collimator on a radiotherapy machine having an x-ray radiation source. The fluence monitoring detector includes a plurality of scintillating optical fibers, each scintillating optical fiber configured to generate a light output at each end thereof in response to incident radiation pattern thereon from the radiation source and multileaf collimator, a plurality of collection optical fibers coupled to the opposing ends of the scintillating optical fibers and operable to collect the light output coming from both ends of each scintillating optical fiber, and a photo-detector coupled to the collection optical fibers and operable to converts optical energy transmitted by the collection optical fibers to electric signals for determining actual radiation pattern information.
