This study proposes the keyhole method in order to improve the time resolution of the proton resonance frequency (PRF) MR temperature monitoring
technique. To evaluate proposed method, the values of Root Mean Square (RMS) error were compared with full phase encoded temperature images. And the
paired t-test was performed for optimization at Keyhole technique. As a result of this study, >32 encoded images were reasonable in 95% confidence level
