Proton resonance frequency shift-based MR thermometry is a promising temperature monitoring approach for thermotherapy but its accuracy is vulnerable to inter-scan motion. Model-based referenceless thermometry has been proposed to address this problem but phase unwrapping is usually needed before the model fitting process. In this paper, a referenceless MR(More)
Referenceless proton resonance frequency (PRF) shift thermometry is robust to B<inf>0</inf> drift and inter-scan tissue displacement in temperature change measurement during minimally invasive thermotherapy procedures such as High Intensity Focused Ultrasound (HIFU). In this method, the baseline phase of the heated region is extrapolated from unheated(More)
