Independent verification of vendor‐issued dosimetric data for 106Ru brachytherapy using diode detectors with traceability to external beam standards for absorbed dose to water

Medical Physics, Volume 53, Issue 4, April 2026.
Abstract Background Independent verification of the manufacturer‐provided dosimetry data for 106Ru ophthalmic brachytherapy applicators is crucial for safe and accurate treatment, yet a standardized, traceable method for clinical absolute dosimetry has been lacking. Purpose This work establishes a complete framework for traceable absorbed dose to water

Kinetic model of radiochemical oxygen depletion (ROD) in FLASH radiotherapy

Medical Physics, Volume 53, Issue 4, April 2026.
Abstract Background The role of oxygen in “Ultra‐High Dose Rate” (UHDR) radiotherapy is currently subject to active debate, due to its importance in the FLASH effect. Radiochemical oxygen depletion (ROD) is used to characterize the removal of oxygen by its interaction with the free radicals produced by the radiation.

31P MRSI Coil Combination Using 23Na Sensitivity Information

Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 1907-1920, April 2026.
ABSTRACT Purpose To optimally combine receive channels for 31P MRSI when the SNR is relatively low using sensitivity maps obtained from 23Na signals. Methods This study utilized a dedicated X‐nuclei 15‐channel head coil array capable of imaging both 23Na and 31P.

RF‐Shielding of Laser‐Cut Venous Stents: Calculations, Simulations, and Experiments

Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2331-2344, April 2026.
ABSTRACT Purpose To develop an analytical model of the RF‐shielding of laser‐cut venous stents for different orientations and stent geometries. Methods Laser‐cut venous stents are modeled as a grid composed of circular and rectangular loops. As these loops are orthogonal they shield different components of the transmit RF field.

A Parallelized 3D Geomechanical Solver for Fluid‐Induced Fault Slip in Poroelastic Media

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 5, Page 2570-2586, 10 April 2026.
ABSTRACT We present a fully implicit formulation of coupled fluid flow and geomechanics for fluid injection/withdrawal in fractured reservoirs in the context of CO2$\textrm {CO}_2$ storage. Utilizing a Galerkin finite‐element approach, both flow and poroelasticity equations are discretized on a shared three‐dimensional mesh.
