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…
Model-based Dynamic 3D MRI Reconstructions using Neural Fields and Tensor Product Expansions
Ray Sheombarsing, Max van Riel, David Heesterbeek +2
Conventional MRI reconstruction methods treat images and coil sensitivities as discrete objects, leading to high memory demands and limited structural awareness that hamper effecti…
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…
An in vivo validation dataset for dynamic volumetric MRI
Max H. C. van Riel, David G. J. Heesterbeek, Martijn Froeling +2
Dynamic volumetric MRI provides valuable information on in vivo motion and biomechanics, with applications spanning cardiac, musculoskeletal, or pulmonary imaging, amongst others.…
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…
