QSM Software Demo

This demo focuses on the processing pipeline of the 2016 QSM Reconstruction Challenge. The aims of the Challenge were (i) to test the ability of QSM algorithms to recover the underlying susceptibility from phase data, and (ii) to provide a dataset that would help benchmark existing and future techniques. The demo begins with raw phase data and applies unwrapping, background removal, transmit phase mitigation, and finishes with fast dipole inversion techniques: TKD and Closed-Form L2-regularization. This replicates the pipeline through which the benchmark susceptibility maps were computed for the Challenge, and can serve as a starting point in future studies.
