Experimental setup and treatment planning. a. The swine is positioned supine on top of a gel pad on the HIFU MRI table (dashed box) housing the HIFU transducer in a water bath. b. Coronal MR image of the swine showing the region of the sacrum where HIFU treatment was applied. The most cranial and caudal locations of the treatment are shown in dashed and solid lines, respectively. Arrows indicate the approximate targeted area. Two types of targeting approach are shown in c and d. Axial MR images (c corresponds to the dashed line, and d - to solid line in figure b) show the overlay of the HIFU beam and prescribed sonications used to treat the right (c) and left (d) SIJ
