Segmentation-free x-ray energy spectrum estimation for computed tomography
, 2016 X-ray energy spectrum plays an essential role in imaging and related tasks. Due to the high photon flux of clinical CT scanners, most of the spectrum estimation methods are indirect and are usually suffered from various limitations. The recently proposed

A Convex Reconstruction Model for X-ray Tomographic Imaging with Uncertain Flat-fields [PDF]
, 2017 Classical methods for X-ray computed tomography are based on the assumption that the X-ray source intensity is known, but in practice, the intensity is measured and hence uncertain.

Dark-field chest x-ray imaging: first experience in patients with alpha1-antitrypsin deficiency
European Radiology Experimental, 2022 Background Spirometry and conventional chest x-ray have limitations in investigating early emphysema, while computed tomography, the reference imaging method in this context, is not part of routine patient care due to its higher radiation dose.
