Prior image based temporally constrained reconstruction (PITCR) algorithm was found to obtain accurate temperature maps with better volume coverage, and spatial, and temporal resolution than other algorithms using highly undersampled data in magnetic resonance (MR) thermometry. PITCR method is compared with the standard temporally constrained reconstruction (TCR) algorithm using ex-vivo pork muscle sample. It was seen that the PITCR method showed superior performance compared to the TCR approach with highly undersampled datasets.
