Photon-counting-detector CT: Technology and clinical applications

Photon-counting-detector CT (PCD-CT) has emerged as a new clinical CT platform with many potential advantages over conventional energy-integrating-detector CT (EID-CT). This talk will provide an overview of the PCD-CT technology and various clinical applications that may benefit from it. Different from EID-CT, the photon-counting detection mechanism in PCD-CT provides more signals and more spectral information about the materials. Potential advantages of PCD-CT include improved radiation dose efficiency, improved spatial resolution, and simultaneous multi-energy multi-contrast agent imaging.
