ABSTRACT
Scintillation fiber optic dosimeters have drawn great attention due to their unique practical advantageous properties including the ability to perform in vivo, real-time, and intracavitary measurements with high spatial resolution because of their small physical size and mechanical flexibility. These features make them ideal candidates for many applications in radiation therapy dosimetry, such as in brachytherapy, intensity-modulated radiation therapy, superficial therapy, stereotactic radiosurgery, proton therapy, and small-field dosimetry. Working principle of optical fibers, characteristics of scintillators and detectors, and issues related to Cherenkov radiation generated in optical fibers are discussed in this chapter.
