We propose a method to remove ultrasound applicator susceptibility temperature error based on PRF-shift phase difference method during MRgHIFU. With this method reference image is not necessary to acquire repetitively when applicator moves position. Therefore tissue cooling down time between reference imaging can be saved. MRgHIFU treatment is simplified and total treatment time is much reduced.
