Photon counting detector (PCD) has been an active research area in recent years. Commercial PCD-CT has been available for routine clinical use since the FDA cleared the first PCD-CT in late 2021, representing a major imaging device advancement for CT. In this lecture, we will discuss the fundamental principles of PCD and explain major benefits of this technology relative to energy integrating detectors which are used on most commercial CT scanners. History and current status of PCD-CT will also be discussed. Potential applications in various clinical areas will be demonstrated using sample phantom and patient images. Challenges and opportunities will also be discussed.
