| Abstract | Purpose: Cherenkov emission (CE) is ubiquitous in external radiotherapy. It is also unique in that it carries the promise of 3D, micrometer‐resolution, perturbation‐free, in‐water dosimetry with a beam quality‐independent detector response calibration. Our aim is to bring CE‐based dosimetry into the clinic and we motivate this here with electron beams. We Monte Carlo (MC) calculate and characterize broad‐beam CE‐to‐dose conversion factors in water for a clinically representative library of electron beam qualities, address beam quality specification and reference depth selection, and develop a preliminary uncertainty budget based on our MC results and relative experimental work of a companion study (Paper I).
Conclusions: By delivering R50-based CE‐to‐dose conversion data and demonstrating the potential for dosimetric uncertainty on the order of 1%, we bring CE‐based electron beam dosimetry closer to clinical realization. |
