ABSTRACT
Cherenkov emission occurs in all media when photons, electrons, or charged particles are delivered for therapy (we refer the reader to Chapter 5 for a review of the basic theoretical concepts). Thus, there is potential to use this emission as a surrogate marker of radiation delivery and deposited dose in the medium. The theoretical and experimental underpinnings of how this signal could be used in radiation therapy dosimetry are outlined here along with the first water phantom and human imaging studies used to illustrate the concepts.
