Fig. 6

Consecutive slices of gross pathology from the experiment 3 demonstrating ablation zones encompassing the posterior of the left and right SIJ. The upper panel shows the planning images for all sonications performed in this experiment, and the corresponding acoustic energy. Changes in muscle tissue extended further when focal targeting approach was used on the left (black double-sided arrows), compared to the near-field targeting approach used on the right. Ligament tips are shown with black arrowheads
