Pediatric Applications of Photon-Counting Detector CT

American Journal of Roentgenology, 2023
Photon-counting detector (PCD) CT represents the most recent generational advance in CT technology. PCD CT has the potential to reduce image noise, improve spatial resolution and contrast resolution, and provide multispectral capability, all of which may be achieved with an overall decrease in the radiation dose. These effects may be used to reduce the

Advanced Neuroimaging With Photon-Counting Detector CT

Investigative Radiology, 2023
Abstract Photon-counting detector computed tomography (PCD-CT) is an emerging technology and promises the next step in CT evolution. Photon-counting detectors count the number of individual incoming photons and assess the energy level of each of them. These mechanisms differ substantially from conventional energy-integrating detectors.

Clinical applications of photon counting detector CT

European 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 detectors, which do not capture information about individual photons in the two-step detection process. In

The technical development of photon-counting detector CT

European Radiology, 2023
Since 1971 and Hounsfield's first CT system, clinical CT systems have used scintillating energy-integrating detectors (EIDs) that use a two-step detection process. First, the X-ray energy is converted into visible light, and second, the visible light is converted to electronic signals.

Characterizing the Heart and the Myocardium With Photon-Counting CT

Investigative Radiology, 2023
Abstract Noninvasive cardiac imaging has rapidly evolved during the last decade owing to improvements in computed tomography (CT)–based technologies, among which we highlight the recent introduction of the first clinical photon-counting detector CT (PCD-CT) system. Multiple advantages of PCD-CT have been demonstrated, including

Neuroimaging Applications of Photon-counting CT

Journal of Computer Assisted Tomography
Photon-counting computed tomography (PCCT) is a new imaging technology that has advanced diagnostic imaging by offering improved spatial and contrast resolution as well as novel spectral imaging capabilities. Unlike conventional CT, which uses energy-integrating detectors, PCCT employs photon-counting detectors that directly measure individual photon ...

Clinical Applications of Photon-counting CT

Radiology, 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 in the literature underpinning the many advantages of PCCT for different clinical applications ...
