Study of prompt gamma and neutron emission for real‐time range verification in proton and carbon‐ion therapy

open access: yesMedical Physics, Volume 53, Issue 7, July 2026.
Abstract Background Accurate range verification is crucial in hadrontherapy to fully exploit the ballistic advantages of charged particles and prevent damage to healthy tissues. Among the proposed approaches, prompt gamma imaging (PGI) has emerged as an effective technique for real‐time monitoring, but its performance is limited by the intense neutron ...

Simulation‐Informed Evaluation of Microvascular Parameter Mapping for Diffusion MR Imaging of Solid Tumours

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 1, Page 387-402, July 2026.
ABSTRACT Purpose We aim to inform the design of new diffusion MRI (dMRI) approaches for microvasculature quantification that enhance the biological specificity of imaging towards cancer. Methods We adopted simulation‐informed modelling of the vascular dMRI signal. We synthesised signals from 1500 synthetic vascular networks, for a variety of protocols (

Motion‐Compensated Diffusion Imaging With Phase‐Contrast for Robust Quantification of Regional Cerebral Blood Flow

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 1, Page 238-246, July 2026.
ABSTRACT Purpose To develop and evaluate a motion‐compensated diffusion imaging with phase‐contrast (MC‐DIP) technique for mitigating errors in regional cerebral blood flow (rCBF) quantification caused by physiological brain motion. Methods Diffusion‐weighted images were acquired in 11 healthy volunteers on a 3.0 T MRI system using three gradient ...

Tuning the Morphology of Self‐Assembled Nanopatterns on MgO(001) Surfaces by Sequential Broad‐Beam Ion Irradiation

open access: yesphysica status solidi (RRL) – Rapid Research Letters, Volume 20, Issue 7, July 2026.
A two‐step approach based on broad‐beam ion irradiation is demonstrated to produce fine‐tuned self‐assembled surface patterns on MgO(001). It shows an efficient route to modifying the crystalline MgO(001) surface topography in a controlled way, making use of its very specific behavior in terms of both the pattern morphology and patterning dynamics.

Simultaneous Deposition of Different Phase‐Change Alloys Through a Nanopillars Shadow Procedure

open access: yesphysica status solidi (RRL) – Rapid Research Letters, Volume 20, Issue 7, July 2026.
A deposition strategy enabling controlled nanoscale stoichiometry modulation in Ge‐Sb‐Te phase‐change materials is presented. Directional elemental fluxes and shadowing effects induced by nanopillar arrays generate distinct Ge‐, Sb‐, and Te‐deficient regions within a single specimen.
