Module qsmart 

QSMART (Quantitative Susceptibility Mapping Artifact Reduction Technique)

This module provides the complete QSMART pipeline including:

• Two-stage QSM reconstruction (whole ROI + tissue only)
• Offset adjustment for combining the two stages
• Integration of SDF background removal with iLSQR inversion
