Dynamic changes of Δ β in ex vivo porcine muscle tissue during HIFU treatment. (A) A total of four lesions were created at every TAP. Δβ values for each lesion were estimated by spatially averaging the Δβ values in ROI, and then those values were further averaged with each other, generating an average profile for each TAP value. For a monitoring duration of 10 min, the duty cycle was 77%, resulting in TAP values of 34, 37, 39, 44, and 49 W, for HIFU treatment time of 40 s. (B) Dynamic changes of Δβ in ex vivo porcine muscle tissue during HIFU treatment presented without the error bars.
