摘要：
A CT scanner apparatus includes an X-ray source mounted on a gantry of the CT scanner apparatus. The CT scanner apparatus also includes a first X-ray detector mounted on the gantry opposite to the X-ray source, and configured to detect X-rays emitted from the X-ray source and transmitted through an object. The CT scanner apparatus also includes a fixed, sparse array of second X-ray detectors. Each of the second X-ray detectors includes a plurality of stacked scintillators and a photosensor adjacent to a sidewall of the stacked scintillators in a side-readout configuration.
