Employing the moving least‐squares aided finite element method (MLS‐FEM) allows detailed thermal analysis in complex porous structures, such as polymeric foams, where the conductive heat transfer mechanism governs in the solid matrix and the convective mechanism dominates within the gas‐filled voids.

Spot size reduction and minibeam creation in a proton PBS nozzle using multipole permanent magnets
Abstract Background Smaller spot sizes in pencil beam scanning (PBS) nozzles are generally desired to allow more conformal treatments and to spare normal tissue and organs at risk. The production of small diameter proton beams, especially proton minibeams, is challenging because long drift spaces in standard PBS nozzles exacerbate effects of MCS and ...

ABSTRACT Purpose To improve the accuracy of diffusion‐weighted powder average signals for diffusion encoding with arbitrary b‐tensors. Methods We identify an intrinsic dihedral (D2) symmetry of diffusion signals for arbitrary diffusion encoding, which defines their natural signal space (a quotient of 3D rotations). Based on this, we propose a method to

Radial Tiny Golden Angle UTE (tyGA‐UTE) for Cardiac MRI in the Small Animal Model
This study validates an 11.7‐T ultra‐high‐field tyGA‐UTE cardiac MRI workflow for murine models, featuring single‐acquisition dual reconstructions for real‐time visualization and quantitative functional assessment. It delivers performance equivalent to standard techniques, excellent reproducibility, and higher efficiency by eliminating repeated scans ...
