(a) High‐resolution B‐mode image of PDA tumor and surrounding organs using L22‐14V probe. The tumor is specified with a dashed white oval shape. The spleen is labeled as S and kidney as K. (b) 2D absolute peak‐to‐peak displacement map of the pancreatic tumor at the end of HIFU ablation (t = 57 s) with the median value of 6.2 μm. (c) 2D Young's modulus map at the end of HIFU ablation (t = 57 s) with median value of 6.2 kPa for tumor part and 4.4 kPa for surrounded part. [Color figure can be viewed at wileyonlinelibrary.com]
