摘要: A CT detector capable of energy discrimination and direct conversion is disclosed. The includes multiple layers semiconductor material with the having varying thicknesses. constructed to be segmented in x-ray penetration direction so as optimize count rate performance well avoid saturation. also variable pixel pitch a flexible binning pixels further enhance performance.
