Detector with non-circular field of view

摘要

A radiation detector includes a slit collimator. A radiation detector receives radiation which has been received in each of the slits. The aspect ratio of the detector is approximately three, and each semiconductor radiation detector has a transverse dimension which is less than that of its respective slit. A reconstruction processor generates an image indicative of the radiation received by the detectors. The detector may be rotated about a fixed axis. Alternately, the detector may be translated in coordination with its rotation to provide a substantially square field of view.
