Wide area surface dosimetry with conformal scintillator array for external beam radiotherapy

In vivo dosimetry is essential for treatment verification in modern radiotherapy, but existing techniques have significant limitations in their logistics of use related to time, accuracy of placement, temporal resolution, and non‐uniform anatomy. Optical scintillation imaging dosimetry has shown potential to address several of these limitations, and the translation to conventional photon external beam radiotherapy was examined with a novel wide area imaging and sensing technique.
