A Subvoxel Correction of Boiling‐Induced Susceptibility Artifacts in Magnetic Resonance Thermometry and Dosimetry for Monitoring Microwave Thermoablation: A Feasibility Study in a Swine Model

Magnetic Resonance in Medicine, Volume 95, Issue 3, Page 1698-1713, March 2026.
ABSTRACT Purpose Real‐time monitoring of microwave liver ablation (MWA) using MRI thermometry can be hindered by boiling‐induced susceptibility artifacts. These artifacts cause large temperature measurement errors that prevent accurate lesion size prediction.

Non‐Invasive, High‐Resolution (1H2O) Metabolic Activity Diffusion Imaging [MADI] of Rat Glioma

NMR in Biomedicine, Volume 39, Issue 3, March 2026.
We employed Metabolic Activity Diffusion Imaging [MADI] and 18FDG‐PET in rats with syngeneic RG2 glioblastoma brain tumors. MADI quantifies kio (the cellular H2O efflux rate constant), cell volume (V), and cell density (ρ), without the use of contrast agents. The kioV product quantifies the rate of water efflux per cell.

Orthogonal Stimulus‐Responsive Ca3Ga2Ge3O12: Pr3+ for Real‐Time X‐Ray Dosimetry and Dynamic Information Encryption

Rare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT Multimodal luminescent materials are crucial for advanced information encryption, real‐time dosimetry, and high‐resolution bioimaging, yet integrating orthogonal stimulus‐responsiveness into a single‐component system is challenging. Herein, we report a Pr3+‐doped Ca3Ga2Ge3O12 (CGGO: Pr3+) garnet phosphor that exhibits orthogonally addressable ...

Impact of Device Architecture on Proton Detection Efficiency in 2D Perovskite Thick Film Detectors

Small, Volume 22, Issue 15, 12 March 2026.
This work shows the role of device architecture in MeV proton detection with 2D perovskite thick (> 1 µm) films. A direct comparison between planar and stacked devices demonstrates that the stacked geometry achieves superior response by enabling more efficient charge collection and better exploitation of the active layer volume, ensuring stable and ...

Machine Learning‐Ready Data Sets for the Analysis and Nowcasting of Atmospheric Radiation at Aviation Altitudes

Space Weather, Volume 24, Issue 3, March 2026.
Abstract Nowcasting and forecasting of the radiation environment in the Earth's lower atmosphere are critical for the safety of aircraft and spacecraft crews and passengers. Currently, this problem is addressed by employing statistical and physics‐based models that take into account particle transport and precipitation.
