Rib Suppression in Digital Chest Tomosynthesis

, 2022
Digital chest tomosynthesis (DCT) is a technique to produce sectional 3D images of a human chest for pulmonary disease screening, with 2D X-ray projections taken within an extremely limited range of angles. However, under the limited angle scenario, DCT contains strong artifacts caused by the presence of ribs, jamming the imaging quality of the lung ...

Consistent performance between medical experts and non‐expert readers in forced‐choice lesion‐detection tasks with PET images

Medical Physics, Volume 52, Issue 11, November 2025.
Abstract Background Labeled data are used to train, validate, and test deep learning model observers (DLMOs) as well as linear model observers, such as channelized Hotelling observers (CHOs), for image quality assessment in many imaging modalities, including PET imaging. Ideally, these annotations would come from clinical readers, but these readers are

Clinical Application of 3D‐Printed Custom Hemipelvic Prostheses With Re‐Entrant Chiral Structure in Reconstruction After Pelvic Tumor Resection

Orthopaedic Surgery, Volume 17, Issue 11, Page 3067-3077, November 2025.
Novel 3D‐printed hemipelvic prostheses incorporating re‐entrant chiral structure achieved 75% porosity while maintaining structural integrity. Clinical outcomes demonstrated 86.7% disease‐free survival and significant functional improvement (MSTS‐93: 14.4→25.7) in pelvic malignancy reconstruction.

Dynamic Properties of Flat-Panel X-Ray Image Sensors With Mercury Iodide Photoconductors Undergoing Repeated X-Ray Irradiation

IEEE Journal of the Electron Devices Society, 2017
A screen-printed mercury iodide (HgI2) photoconductor for digital tomosynthesis exhibits considerably reduced signals when subjected to consecutive exposures to X-ray irradiation. This behavior accounts for the trapping of charges generated on previous X-
