Abstract: X-rays are a ubiquitous imaging modality in clinical diagnostics and industrial inspections, thanks to their high penetration power. Conventional transmission-based x-ray radiography or computed tomography systems collect approximately 103–104 counts per pixel to ensure sufficient… read more here.

DOI: 10.1109/access.2020.2977096
Abstract: The development of energy-resolving photon-counting detectors provides a new approach for obtaining spectral information in computed tomography. However, the responses of different photon counting detector pixels can be inconsistent, which will always cause stripe artefacts… read more here.
