Bloch-simulator-based joint reconstruction and field inhomogeneity estimation with plug-and-play denoising diffusion model

A non-transitory computer implemented storage medium, including machine-readable instructions stored therein for Bloch-simulator-based joint reconstruction and field inhomogeneity estimation, the instructions when executed by at least one processor, cause the processor to:

• acquire MR data of a patient acquired in an imaging procedure using a MR protocol;
• input the MR data and the MR protocol into a MR simulator configured to compute tissue parameters and the field inhomogeneity using a joint reconstruction framework, wherein the joint reconstruction framework alternates optimizations of a field inhomogeneity map and tissue parameters using a plug-and-play diffusion framework;
• and
• output one or more tissue parameter maps and a field inhomogeneity map for the imaging procedure.
