Low-cost, multislice CT detector with multiple operating modes

摘要

One aspect of the present invention is a detector array for a computed tomographic imaging system having a z-direction corresponding to an image slice thickness direction and that is arc-shaped in a direction transverse to the z-direction. The detector array has a plurality of detector modules configured so that the detector array has active regions of differing thicknesses.This detector array embodiment provides an optimized detector array for certain imaging situations, for example, in cardiac imaging applications in which increased coverage is required only in a relatively small central portion of a field of view.
