VIDEO: Example of photo-counting cardiac CT

Siemens Healthineers showed examples of cardiac computed tomography (CT) from its new Naeotom Alpha photon-counting CT scanner at the American College of Cardiology (ACC) 2022 meeting. The CT system was the first photon-counting CT scanner to be approved commercially, cleared by the FDA in 2021. This example shows the technology can clearly see inside coronary arteries that have heavy calcium burden. In conventional scans, the calcium would cause blooming artifacts and make it very difficult to assess the vessel lumen.
