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 [email protected] to get a link
