摘要

Computed tomography (CT) is widely used in medical imaging to reconstruct a 3-D image of a patient. To limit the radiation dose applied to patients, researches focus on reducing the statistical noise or increasing the contrast in the image. Recently, time-correlated single-photon counting (TCSPC) CT—also known as time-of-flight (TOF) CT—has been proposed to reduce scatter contribution to images an...
