Photon-counting CT represents the most significant technology advance in computed tomography since the introduction of multi-slice CT. By replacing conventional energy-integrating detectors with photon-counting detectors, the technology delivers substantially higher spatial resolution, improved spectral imaging capability, reduced radiation dose, and elimination of electronic noise — enabling clinical applications previously not achievable with conventional CT. Siemens Healthineers' NAEOTOM Alpha is the first commercial photon-counting CT system and has established clear technology leadership. GE HealthCare and Philips are developing competitive responses.
