Abstract
A volumetric stationary CT system has at least one stationary array of x-ray detectors extending proximate at least a portion of an imaging volume, at least one stationary x-ray source proximate the stationary array or arrays of x-ray detectors, and a collimator having a slit with a non-uniform opening width. The collimator is intermediate the stationary x-ray source and the stationary array of x-ray detectors. The result is a uniform flux normal to the detector array across the entire length thereof.
