Color Cherenkov imaging of clinical radiation therapy

ABSTRACT: Color vision is used throughout medicine to interpret the health and status of tissue. Ionizing radiation used in radiation therapy produces broadband white light inside tissue through the Cherenkov effect, and this light is attenuated by tissue features as it leaves the body. In this study, a novel time-gated three-channel camera was developed for the first time and was used to image color Cherenkov emission coming from patients during treatment. The spectral content was interpreted by comparison with imaging calibrated tissue phantoms. Color shades of Cherenkov emission in radiotherapy can be used to interpret tissue blood volume, oxygen saturation and major vessels within the body. A novel three-channel intensified camera capable of imaging Cherenkov emission in full color was developed, allowing for sensitivity to in vivo biological tissue information during radiotherapy.
