TITLE: Photon-counting computed tomography at UVic
ABSTRACT:
In 2021, Siemens announced that their Naeotom Alpha was the first photon-counting computed tomography (PCD-CT) scanner approved for clinical use in the United States and Europe. However, to date it is still quite unclear what are the diagnostic benefits of PCD-CT, as only limited clinical data is available. In this talk, I will first present the principles of PCD-CT and compare them to conventional CT acquired with energy-integrating detectors (EIDs). Then some clinical PCD-CT images will be shown and potential applications discussed. The experimental table-top PCD-CT system in the X-ray Cancer Imaging and Therapy Experimental (XCITE) lab at the University of Victoria will be introduced next. Its applications for K-edge imaging, multi-contrast imaging, metal artifact reduction and high-resolution stent imaging will be presented. At the end of the talk, the challenges of PCD-CT imaging will be summarized.
