MR thermometry based on proton resonance frequency shift (PRFS) is a promising method for noninvasive temperature measurement. In this method, phase differential information is highly needed during the acquisition and reconstruction process. Previous research has demonstrated that the correlation between different scans could be used for reconstruction from under-sampled data. Based on this demonstration, a method for accelerated temperature mapping using sharable information from reference scans is proposed in our research. Phantom experiments have demonstrated the accuracy and feasibility of our new framework in comparison with previous parallel imaging methods and parallelCCS methods.
