Abstract
A radiation-based imaging system includes a collimator configured to filter radiation emitted from a target object, the collimator including a plurality of apertures non-uniformly distributed on the collimator. A largest acceptance angle of the plurality of apertures is not larger than 15°. The radiation-based imaging system further includes a detector for detecting the radiation that has passed through the collimator. The collimator is spaced from the detector such that a point on a top surface of the detector that faces the collimator is simultaneously illuminated by two or more of the plurality of apertures.
