Accelerated Real-time Cine and Flow under In-magnet Staged Exercise
Conclusions: The study demonstrates that RT ExCMR with in-magnet exercise is a feasible and effective method for dynamic cardiac function monitoring during exercise.
Deep Image prior with StruCtUred Sparsity (DISCUS) for dynamic MRI reconstruction
In the second study, we use data from a realistic late gadolinium enhancement (LGE) phantom to compare DISCUS with compressed sensing (CS) and DIP and to demonstrate the positive impact of group sparsity.
Motion-robust free-running cardiovascular MRI
For validation, CORe is first compared to traditional compressed sensing (CS), robust regression (RR), and another outlier rejection method using two simulation studies.
Technical Report (v1.0)--Pseudo-random Cartesian Sampling for Dynamic MRI
For an effective application of compressed sensing (CS), which exploits the underlying compressibility of an image, one of the requirements is that the undersampling artifact be incoherent (noise-like) in the sparsifying transform domain.
Cardiac and respiratory motion extraction for MRI using Pilot Tone-a patient study
Purpose: We seek to evaluate the accuracy and reliability of the cardiac and respiratory signals extracted from PT in patients clinically referred for cardiovascular MRI with the image-derived signals as the reference.
Fully Self-Gated Whole-Heart 4D Flow Imaging from a Five-Minute Scan
ReVEAL4D is validated using data from eight healthy volunteers and two patients and compared with a compressed sensing technique, L1-SENSE.
Automatic Extraction and Sign Determination of Respiratory Signal in Real-time Cardiac Magnetic Resonance imaging
A complete heartbeat from each slice is then used for cardiac function quantification.
