Structured detectors and detector systems for radiation imaging
Detector module designs for radiographic imaging include first and second layers of scintillator rods or pixel arrays oriented in first and second directions. The first and second directions are transversely oriented to define a light sharing region between the first and second layers. Encoding features may be disposed in, on or between the first and second layers, and configured to modulate propagation of optical signals therealong or therebetween.

Radiation-induced false count mitigation and detector cooling
An inspection system with radiation-induced false count mitigation includes an illumination source configured to illuminate a sample and a liquid-cooling coincidence detector, which includes an illumination detector to detect illumination from the sample, a liquid-cooling device for regulating a temperature of the illumination detector via a liquid, and photodetectors to detect light generated in the liquid in response to particle radiation. The liquid-cooling coincidence detector may also include controllers to identify a set of illumination detection events based on an illumination signal received from the illumination detector, identify a set of radiation detection events based on radiation signals received from the photodetectors, compare the set of radiation detection events to the set of illumination detection events to identify a set of coincidence events, and exclude the set of coincidence events from the set of illumination detection events to generate a set of identified features on the sample.
Radiation dosage monitoring system
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.
