Representative results of a canine soft tissue sarcoma (STS) specimen (a) before treatment, (b) after 1st iMT, and (c) after 2nd iMT. (I) Structural OCT images and (II) reconstructed Young’s modulus ($E$) maps. (III) Photographs obtained (left) before and (right) after each treatment; thermal images acquired at the (left) 0th and (right) 4th min of each treatment. White arrows in (I) and (III) indicate the locations of the magnetic thermoseed. (IV) (Bottom) Post-treatment Masson Trichrome-stained histology and (top) a zoomed-in area. Collagen is stained blue. The ablation zone was delineated with the dashed line. (V) Shear wave propagation captured at three temporal instants were also visualized (full video shown in Visualization 3 ^{(395.4KB, mp4)} at 120 fps).
