The recent introduction of photon-counting CT has brought about a lot of excitement in the community. This new technology will not only bring important advances in current clinical applications but has the potential to introduce new applications for CT imaging. Of course, new technology not only opens up new frontiers, but always brings about new challenges to achieve its full potential, both in hardware and software.
During this session, we will review the technological and physical aspects of photon-counting CT systems, discuss the new applications that could be introduced in the future, and the challenges and opportunities that these advances will bring about.
