Tools for reconstructing Pulmonary MRI datasets to manage motion
Current tools are built for 3D ultrashort echo time (UTE) MRI acquisitions with pseudo-random spatio-temporal sampling
Requirements
- BART https://mrirecon.github.io/bart/ - Sample data has been tested with BART v.0.4.00, please install version later than v.0.4.00 https://github.com/mrirecon/bart/releases/
- MATLAB
- Typically requires 100GB RAM, for 256256256 matrix size, 8 channel, 4 motion phase.
Current features
- Supports center-out k-space trajectories (e.g. UTE with radial, cones)
- Soft-gating reconstruction
- Motion-resolved reconstruction
- Dynamic Image Navigator reconstruction
Sample Data
- An anonymized sample dataset from a volunteer is available on request to test out the methods - please contact peder.larson@ucsf.edu to get a link
