Task‐based evaluation of axial and multiplanar reconstructions in computed tomography: A volumetric analysis of spatial resolution, noise, and detectability

open access: yesJournal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Background Multiplanar reconstructions (MPRs) are an essential clinical tool for interpreting complex 3D anatomy, offering improved diagnostic accuracy in computed tomography (CT). However, image quality can be impaired by the inappropriate use of reconstruction parameters for primary axial slices.

Clinical in‐vivo dosimetry for total skin electron therapy using gafchromic™ EBT4 film

open access: yesJournal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Background Total skin electron therapy (TSET) is a standard treatment for cutaneous T‐cell lymphoma. Due to the complex patient positioning and irregular body contours, robust in‐vivo dosimetry (IVD) is essential to verify dose uniformity. While thermoluminescent dosimeters (TLDs) are traditional standard, their utility is hindered by labor ...

Phantom evaluation of small‐pixel effect in ultra‐high‐resolution photon‐counting CT: Noise texture and high‐contrast spatial resolution

open access: yesJournal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Background Ultra‐high‐resolution (UHR) photon‐counting CT (PCCT) with small‐pixel detectors improves resolution and noise, but its dependence on diverse imaging conditions remains insufficiently characterized. Purpose To systematically evaluate the small‐pixel effect in UHR PCCT by assessing noise properties and high‐contrast spatial ...

Task‐based image quality and dosimetric validation of HyperSight CBCT for adaptive radiotherapy

open access: yesJournal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Background Cone‐beam computed tomography (CBCT) is increasingly used in adaptive radiotherapy (ART), yet the dosimetric accuracy and image quality of advanced CBCT imaging platforms—such as Halcyon HyperSight 4.0 (HH), which combines an upgraded detector panel with advanced iterative reconstruction, scatter‐correction, and metal‐artifact ...

A l'occasion d'un trentenaire : sur l'interprétation des figurations anthropomorphes du paléolithique supérieur

open access: yes, 1939
Introduction : Il y a trente ans notre regretté collègue, mon beau-père, P. Bourrinet, recueillait à Teyjat (Dordogne), au cours de ses fouilles de l'Abri Mège, un " bâton de commandement orné de figures animales et de personnages semi-humains gravés. Ce remarquable objet, découvert clans un niveau magdalénien qui avait déjà donné un bel outillage en ...
