Multi-Mounted X-Ray Computed Tomography. [PDF]

open access: yesPLoS ONE, 2016
Most existing X-ray computed tomography (CT) techniques work in single-mounted mode and need to scan the inspected objects one by one. It is time-consuming and not acceptable for the inspection in a large scale.

Potential of ultra-high-resolution photon-counting CT of bone metastases: initial experiences in breast cancer patients

open access: yesnpj Breast Cancer, 2021
Conventional CT scanners use energy-integrating detectors (EIDs). Photon-counting detector (PCD) computed tomography (CT) utilizes a CT detector technology based on smaller detector pixels capable of counting single photons and in addition discriminating

X-ray induced acoustic computed tomography

open access: yesPhotoacoustics, 2020
X-ray imaging has proved invaluable in medical diagnoses and non-destructive testing (NDT) in the past century. However, there remain two major limitations: radiation harm and inaccessibility to the sample.
