Module inversion 

Dipole inversion methods for QSM

This module provides various methods to solve the inverse problem of estimating magnetic susceptibility from local field measurements.

Methods include:

• TKD: Truncated k-space division (fast, simple)
• TSVD: Truncated SVD (zeros small values)
• Tikhonov: L2 regularization (closed-form)
• TV: Total variation regularization via ADMM (iterative)
• NLTV: Nonlinear TV with iterative reweighting
• RTS: Rapid two-step method
• MEDI: Morphology-enabled dipole inversion
• TGV: Total Generalized Variation (single-step from wrapped phase)
