Fast 3D 31P B1+ mapping with a weighted stack of spiral trajectory at 7 T

Salomé Sophie Célestine Baup, Lijing Xin, Katarzyna Pierzchala, Daniel Wenz, Mark Stephan Widmaier, Ying Xiao, Zhiwei Huang, Antonia Kaiser

Purpose: Phosphorus MRS (31P MRS) enables noninvasive assessment of energy metabolism, yet its application is hindered by sensitivity limitations. To overcome this, often high magnetic fields are used, leading to challenges such as spatial (Formula present ...

Development of performance portable spline solver for exa-scale plasma turbulence simulation

Emily Louise Bourne

This paper describes the development of performance portable spline building kernels on top of Kokkos-kernels. We wish to solve a single matrix equation with multiple right-hand sides. This problem is quite unique and thus neither Kokkos-kernels (direct me ...

In-Silico Trained AI for Enhanced T2Spectrum Imaging and Myelin Water Fraction Mapping in Preclinical 7T MRI

Jean-Philippe Thiran, Erick Jorge Canales Rodriguez, Thomas Yu

This study introduces a Machine Learning (ML) approach for estimating the T2 spectrum and myelin water fraction (MWF) using multi-echo T2 (MET2) data from preclinical 7T Magnetic Resonance Imaging (MRI) scanners. ML methods have shown promise in MWF estima ...

ROBUST RADIAL BASIS FUNCTION INTERPOLATION BASED ON GEODESIC DISTANCE FOR THE NUMERICAL COUPLING OF MULTIPHYSICS PROBLEMS

Alfio Quarteroni

Multiphysics simulations frequently require transferring solution fields between subproblems with nonmatching spatial discretizations, typically using interpolation techniques. Standard methods are usually based on measuring the closeness between points by ...

SPARCQ: A new approach for fat fraction mapping using asymmetries in the phase-cycled balanced SSFP signal profile

Tobias Kober, Tom Hilbert, Katarzyna Pierzchala

Purpose: To develop SPARCQ (Signal Profile Asymmetries for Rapid Compartment Quantification), a novel approach to quantify fat fraction (FF) using asymmetries in the phase-cycled balanced SSFP (bSSFP) profile. ...
