MR Simulation with Phase Distribution Graphs: Off-Resonant Pulse Response and Slice-Selection
Felix Dietz, Jonathan Endres, Simon Weinmueller +2
Purpose: Phase Distribution Graphs were introduced as a powerful tool for on-resonant MRI simulations. Herein, we extend the concept beyond the assumptions of hard and on-resonant…
Agentic MR sequence development: leveraging LLMs with MR skills for automatic physics-informed sequence development
Moritz Zaiss, Amr Aly, Jonathan Endres +3
Purpose: Novel MR sequence developments still today allow generation of new diagnostic tools or novel imaging biomarkers. Programming MRI pulse sequences, however, is time-consumin…
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…
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…
