Free-Running Time-Resolved First-Pass Myocardial Perfusion Using a Multi-Scale Dynamics Decomposition: CMR-MOTUS
Thomas E. Olausson, Maarten L. Terpstra, Niek R. F. Huttinga +7
We present a novel approach for the reconstruction of time-resolved free-running first-pass myocardial perfusion MRI, named CMR-MOTUS. This method builds upon the MR-MOTUS framewor…
Real-time myocardial landmark tracking for MRI-guided cardiac radio-ablation using Gaussian Processes
Niek R. F. Huttinga, Osman Akdag, Martin F. Fast +5
The high speed of cardiorespiratory motion introduces a unique challenge for cardiac stereotactic radio-ablation (STAR) treatments with the MR-linac. Such treatments require tracki…
Towards retrospective motion correction and reconstruction for clinical 3D brain MRI protocols with a reference contrast
Gabrio Rizzuti, Tim Schakel, Niek R. F. Huttinga +3
Motion artifacts often spoil the radiological interpretation of MR images, and in the most severe cases the scan needs be repeated, with additional costs for the provider. We discu…
Gaussian Processes for real-time 3D motion and uncertainty estimation during MR-guided radiotherapy
Niek R. F. Huttinga, Tom Bruijnen, Cornelis A. T. van den Berg +1
Respiratory motion during radiotherapy causes uncertainty in the tumor's location, which is typically addressed by an increased radiation area and a decreased dose. As a result, th…
Real-time non-rigid 3D respiratory motion estimation for MR-guided radiotherapy using MR-MOTUS
Niek R. F. Huttinga, Tom Bruijnen, Cornelis A. T. van den Berg +1
The MR-Linac is a combination of an MR-scanner and radiotherapy linear accelerator (Linac) which holds the promise to increase the precision of radiotherapy treatments with MR-guid…
Non-rigid 3D motion estimation at high temporal resolution from prospectively undersampled k-space data using low-rank MR-MOTUS
Niek R. F. Huttinga, Tom Bruijnen, Cornelis A. T. van den Berg +1
With the recent introduction of the MR-LINAC, an MR-scanner combined with a radiotherapy LINAC, MR-based motion estimation has become of increasing interest to (retrospectively) ch…
Model-based reconstruction of non-rigid 3D motion-fields from minimal -space data: MR-MOTUS
Niek R. F. Huttinga, Cornelis A. T. van den Berg, Peter R. Luijten +1
Estimation of internal body motion with high spatio-temporal resolution can greatly benefit MR-guided radiotherapy/interventions and cardiac imaging, but remains a challenge to dat…
Opening a new window on MR-based Electrical Properties Tomography with deep learning
Stefano Mandija, Ettore F. Meliadò, Niek R. F. Huttinga +2
Electrical properties (EPs) of tissues, conductivity and permittivity, are modulated by the ionic and water content, which change in presence of pathologies. Information on tissues…
