20. Direct signal control without Fourier coefficients

Dr Kurt Majewski (Siemens AG, DAI R ORD-DE)

20/05/2026, 11:00

The well known direct signal control (DSC) approach allows us to optimize excitation voltages of a MRI pulse sequence in such a way that the overall transverse magnetization of a spin ensemble has desired values at a number of signal readout times. In this approach the overall transverse magnetization is calculated with the help of an approximate solution of the Bloch equations and...

13. Arterial spin labeling MRI with radial sampling: end-to-end open-source sequence design and image reconstruction using BART

Ms Viktoria Buchegger (Institute of Biomedical Imaging, Graz University of Technology, Graz, Austria)

Introduction Arterial spin labeling (ASL) is a promising non-invasive perfusion imaging technique, but its reproducibility across platforms remains limited due to the lack of standardized, end-to-end pipelines. Although consensus guidelines exist, implementation variability persists. The Berkeley Advanced Reconstruction Toolbox (BART) is a free and open-source computational MRI framework for...

33. Open-source quantitative MRI: combined acquisition and reconstruction

Mr Daniel Mackner (Graz University of Technology)

20/05/2026, 11:50

This work presents an open-source framework that integrates MRI sequence design, execution, and model-based reconstruction into a single reproducible workflow within the BART toolbox. The motivation is to address reproducibility challenges in quantitative MRI (qMRI), where both sequence implementation and reconstruction details are often difficult to replicate due to proprietary software and...

31. MRI sequences: practical aspects of system integration

Mr Philip Schaten (TU Graz)

20/05/2026, 12:15

Open-Source software such as pypulseq and BART have immensely improved MRI sequence design and image reconstruction. Nevertheless, working with a clinical MRI scanner still poses challenges. We present solutions for bringing open source sequences and image reconstruction to the scanner. An MRI sequence describes the sequence of events that is played out by the scanner hardware during an MRI...
