A toolbox of chi-separation for magnetic susceptibility source separation

The susceptibility maps generated by QSM and $χ$-separation show magnetic susceptibility distributions, which have been proposed as important biomarkers for brain disorders. However, susceptibility mapping requires a complicated multi-step procedure that is difficult for inexperienced researchers. There is a need to design a convenient application that can easily conduct susceptibility mapping. In this work, we developed a MATLAB based GUI software, called the ‘$χ$-separation toolbox’ that generates high-quality susceptibility maps in just a few clicks. The GUI of our toolbox is intuitive and user-friendly that it helps researchers to conduct QSM and $$χ$-separation processing without difficulty.
