ABSTRACT:
An imaging system includes a linear detector array which measures x-rays passing through a patient from an x-ray source. A mask disposed over the detector array has staggered segments that block x-rays and divide the detector array into a pair of slice planes. Signals from the detector elements receiving x-rays in respective ones of the two slice planes are used to separately reconstruct a slice image for each of the two slice planes.
