Real‐time cardiac cine MRI: A comparison of a diffusion probabilistic model with alternative state‐of‐the‐art image reconstruction techniques for undersampled spiral acquisitions

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose Electrocardiogram (ECG)‐gated cine imaging in breath‐hold enables high‐quality diagnostics in most patients but can be compromised by arrhythmia and inability to hold breath. Real‐time cardiac MRI offers faster and robust exams without these limitations.

Functional inequalities involving Bessel and modified Bessel functions of the first kind

Expositiones Mathematicae, 2008
AbstractIn this paper, we extend some known elementary trigonometric inequalities, and their hyperbolic analogues to Bessel and modified Bessel functions of the first kind. In order to prove our main results, we present some monotonicity and convexity properties of some functions involving Bessel and modified Bessel functions of the first kind. We also

gammaSTAR: A framework for the development of dynamic, real‐time capable MR sequences

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose To present the real‐time capability and advanced MR sequence library of the MR sequence development framework gammaSTAR. Methods The presented platform consists of four different components: (1) a frontend for sequence development combined with a Python backend for sequence generation; (2) a Lua backend for the creation of hardware ...

Modeling the effect of in‐plane magnetic field gradients on asymmetric spin‐echo images with echo‐planar imaging readout

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose To describe the impact of macroscopic magnetic field gradients (MFGs) in the phase‐encoding direction on MR images acquired with an asymmetric spin echo (ASE) sequence with echo‐planar imaging (EPI) readout. Methods In EPI, the center of k‐space is read out at a shifted time point in the presence of phase‐encoding direction MFGs.

Seismic Bearing Capacity of Shallow Foundations in Anisotropic Non‐Homogeneous Soils Under Torsional Waves and Parameter Uncertainty

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT The purpose of the present paper is to investigate the effects of the torsional wave propagation and the soil‐earthquake parameter uncertainties on the seismic bearing capacity of shallow foundations in anisotropic non‐homogeneous media.
