Abstract

Optical fiber-based probes are promising candidates for many applications in radiotherapy dosimetry and quality assurance due to their unique properties including the ability to perform in vivo, real-time, and intracavitary measurements with high spatial resolution. However, a significant issue related to fiber optic dosimetry of photon and proton therapies is ÄŒerenkov radiation generated in the optical fibers. We have designed, fabricated, and characterized fiber probes composed of solid core and hollow core fibers in conjunction with scintillators for radiotherapy dosimetry. Using a spectroscopic method to subtract the ÄŒerenkov contamination, we showed good agreement between our fiber probe and standard ionization chamber measurements.
