On the use of polychromatic cameras for high spatial resolution spectral dose measurements

Abstract: Objective: Despite the demonstrated benefits of hyperspectral formalism for stem effect corrections in the context of fiber dose measurements, this approach has not been yet translated into volumetric measurements where cameras are typically used for their distinguishing spatial resolution. This work investigates demosaicing algorithms for polychromatic cameras based spectral imaging. Approach: The scintillation and Cherenkov signals produced in a radioluminescent phantom are imaged by a polychromatic camera … Show more
