    Photon-counting coronary CT angiography (cCTA) is a new technology that improves non-invasive coronary artery imaging.

  • 2

    The novel ZeeFree reconstruction algorithm aims to reduce respiratory and cardiac motion artifacts in photon-counting cCTA.

  • 3

    Ultra-high-resolution cCTA enhances imaging for patients with severe coronary calcifications and stent imaging.

    The study evaluates the image quality and diagnostic utility of the ZF algorithm compared to Standard and TrueStack algorithms.

  • 5

    The ZF algorithm utilizes non-rigid registration and Gaussian smoothing to improve image alignment and reduce noise.
