Abstract
A collimator is provided for reducing aliasing artifacts in images generated in an X-ray imaging system, such as a computed tomography (CT) imaging system. In one embodiment, a collimator comprises a plurality of high attenuating regions interleaved with a plurality of low attenuating regions, with each high attenuating region having a non-uniform transition profile and configured to be aligned with a respective inactive region of a respective channel of an X-ray detector of an X-ray imaging system. In another embodiment, a CT imaging system, comprising an X-ray source configured to project X-rays towards a patient; an X-ray detector configured to receive attenuated X-rays passing through the patient; and a collimator positioned between the patient and the X-ray detector and configured to non-uniformly attenuate the X-rays, the collimator having bell shaped plates, each of the plates separated by a gap.
