Accelerated susceptibility-driven positive contrast MRI reconstruction based on primal-dual optimization with minimal parameter tuning
The susceptibility-driven positive contrast imaging technique based on PD regularization demonstrates faster convergence, superior image quality, and easier parameter adjustment compared to conventional CG methods. The speed of reconstruction can be further improved by GPU acceleration.
