Equivariant conditional diffusion model for head and neck CT image synthesis from CBCT

Medical Physics, Volume 53, Issue 8, August 2026.
Abstract Background Cone‐beam computed tomography (CBCT) is a commonly used modality for image guided radiotherapy (IGRT). It offers real time anatomical visualization with low acquisition cost and dose. Nevertheless, photon scattering and beam hindrance lead CBCT images to suffer from several artifacts.

Experimental quantification of frame‐level active window duration and duty cycle in high frame rate x‐ray detectors

Medical Physics, Volume 53, Issue 8, August 2026.
Abstract Background Detector frame rate is commonly used as the primary metric to characterize the temporal behavior of x‐ray detectors in medical imaging systems. However, frame rate alone specifies only the sampling rate of image frames and does not determine how x‐ray interaction signals are temporally integrated to form the measured signal within ...

Magnetic resonance imaging safety‐driven, heat‐mitigating design for a magnetic resonance imaging‐guided, magnetically actuated robotic catheter

Medical Physics, Volume 53, Issue 8, August 2026.
Abstract Background Metallic components in magnetic resonance imaging (MRI)−guided robotic catheters, such as leadwires and microcoils, can interact with the scanner's radiofrequency (RF) fields, causing heating via the antenna effect and Joule heating, leading to localized temperature rises and an increased risk of thermal injury.

Late Cenozoic Convergence Between the Pamir and the Tianshan Revealed by Low‐Temperature Thermochronology

Tectonics, Volume 45, Issue 8, August 2026.
Abstract The Cenozoic India–Eurasia collision drove widespread deformation across Central Asia, culminating in northward indentation of the Pamir and its eventual contact with the South Tianshan. However, the timing and kinematics of Pamir–Tianshan convergence, as well as its influence on regional topography and climate, remain debated. Here, we report
