Photon-counting statistics-based support vector machine with multi-mode photon illumination for quantum imaging

open access: yesScientific Reports, 2022
We propose a photon-counting-statistics-based imaging process for quantum imaging where background photon noise can be distinguished and eliminated by photon mode estimation from the multi-mode Bose–Einstein distribution.

Clinical Applications of Photon-counting CT: A Review of Pioneer Studies and a Glimpse into the Future.

open access: yesRadiology, 2023
CT systems equipped with photon-counting detectors (PCDs), referred to as photon-counting CT (PCCT), are beginning to change imaging in several subspecialties, such as cardiac, vascular, thoracic, and musculoskeletal radiology. Evidence has been building

Clinical Applications of Photon Counting Detector CT

open access: yesEuropean Radiology, 2023
The X-ray detector is a fundamental component of a CT system that determines the image quality and dose efficiency. Until the approval of the first clinical photon-counting-detector (PCD) system in 2021, all clinical CT scanners used scintillating ...
