MR-zero meets FLASH -- Controlling the transient signal decay in gradient- and rf-spoiled gradient echo sequences
Simon Weinmüller, Jonathan Endres, Nam Dang +2
Abstract Purpose The complex signal decay during the transient FLASH MRI readout can lead to artifacts in magnitude and phase images. We show that target-driven optimization of ind…
Enhanced and Robust Contrast in CEST MRI: Saturation Pulse Shape Design via Optimal Control
Clemens Stilianu, Christina Graf, Markus Huemer +5
Purpose: To employ optimal control for the numerical design of CEST saturation pulses to maximize contrast and stability against inhomogeneities. Theory and Methods: We appli…
BMapEst: Estimation of Brain Tissue Probability Maps using a Differentiable MRI Simulator
Utkarsh Gupta, Emmanouil Nikolakakis, Moritz Zaiss +1
Reconstructing digital brain phantoms in the form of voxel-based, multi-channeled tissue probability maps for individual subjects is essential for capturing brain anatomical variab…
MR sequence design to account for non-ideal gradient performance
Daniel J West, Felix Glang, Jonathan Endres +4
MRI systems are traditionally engineered to produce close to idealized performance, enabling a simplified pulse sequence design philosophy. An example of this is control of eddy cu…
Image space formalism of convolutional neural networks for k-space interpolation
Peter Dawood, Felix Breuer, Istvan Homolya +4
Purpose: Noise resilience in image reconstructions by scan-specific robust artificial neural networks for k-space interpolation (RAKI) is linked to nonlinear activations in k-space…
