Abstract
A radiation dosage monitoring system comprising a 3D camera operable to obtain images of a patient undergoing radiation treatment, the 3D camera being operable to detect Cherenkov radiation and any subsequent secondary and scattered radiation originating due the initial Cherenkov radiation emitted from a surface of the patient when the patient is irradiated by a radiation beam; and a processing module operable to process the images obtained by the 3D camera utilizing data indicative of chromophores present in a patient's skin to apply a correction factor to such images to account for absorption of Cherenkov radiation by chromophores in the skin when utilizing the images to generate a representation of radiation applied to the surface of the patient.
