Fast ungated five-dimensional cardiac MRI on a 1.5 T MR-linac for MRI-guided radiotherapy
M. L. Terpstra, T. E. Olausson, M. M. N. Aubert +4
Background: Stereotactic arrhythmia radio-ablation (STAR) for patients with ventricular tachycardia is currently limited by complex cardiorespiratory motion. Current 5D-MRI motion…
Fast undersampled dynamic MRI reconstruction using explicit representation learning with Gaussian splatting
M. L. Terpstra, C. A. T. van den Berg
Motivation: Quickly obtaining high-quality MRI from accelerated acquisitions is important to mitigate motion artifacts, maintain patient comfort, and improve clinical efficiency. G…
Feasibility of Continuous Ventricular Volumetric Quantification in Arrhythmias using Real-Time 3D CMR-MOTUS
Thomas E. Olausson, Maarten L. Terpstra, Rizwan Ahmad +7
Conventional cardiovascular magnetic resonance (CMR) cine imaging combines data across multiple heartbeats, an assumption that can fail in arrhythmia because beat-to-beat variation…
Quasi-static in vivo elastography from internal displacement information only
David G. J. Heesterbeek, Max H. C. van Riel, Ray S. S. Sheombarsing +4
As disease often alters the structural properties of soft tissue, noninvasive elastography techniques have emerged to quantitatively assess in vivo mechanical properties. Magnetic…
