Coronary CT Angiography with Photon-counting CT: First-In-Human Results.

Radiology, 2022
Background Spatial resolution, soft-tissue contrast, and dose-efficient capabilities of photon-counting CT (PCCT) potentially allow a better quality and diagnostic confidence of coronary CT angiography (CCTA) in comparison to conventional CT.

Self-Powered Perovskite Photon Counting Detectors

Nature, 2023
Metal-halide perovskites (MHPs) have been successfully exploited for converting photons to charges or vice versa in applications of solar cells, light-emitting diodes and solar fuels^ 1 – 3 , for which all these applications involve strong light. Here we
