A collimator for a detector, much like a 2D anti-scatter collimator of a computed tomography system, this system places a 2D collimator (1) between the object (2) and the detector (3). This system uses the 2D collimator in the place of a lens in a camera body, it is used to gather scattered photons (4), so the source (5) of the electromagnetic spectrum is not required to be placed in alignment with the 2D collimator. |
