Spectral Photon Counting CT: Imaging Algorithms and Performance Assessment
IEEE Transactions on Radiation and Plasma Medical Sciences（2021）
摘要
Photon counting X-ray detectors (PCDs) with spectral capabilities have the potential to revolutionize computed tomography (CT) for medical imaging. The ideal PCD provides accurate energy information for each incident X-ray, and at high spatial resolution. This information enables material-specific imaging, enhanced radiation dose efficiency, and improved spatial resolution in CT images. In practic...
