Abstract
An imaging detector includes a collimator, a scintillator and a photodiode array. The collimator directs radiation to scintillator segments having apertures substantially matched to collimator apertures. Optical reflectors and heavy metal septa between the segments reduce light and radiation scatter between the segments, respectively. Photodiode array elements with active areas substantially matched to the scintillator segment apertures detect light generated when the radiation interacts with the scintillator. A cooler, a low noise photodiode array and readout electronics improve the signal-to-noise ratio of the imaging system in specific embodiments.
