Hemiablation of the prostate. The upper panel transverse image shows the HIFU ablation targeted only for the left half of the gland. The lower panel images are reference images taken prior to tissue ablation process. The prostate is ablated with a 4 cm focal length transducer with TAP of 37 watts. Thermocouple needle T3 is displayed as a hyperechoic line within the focal zone of the HIFU transducer. Another thermocouple needle is outside the focal zone (seen on the transverse image-marked with an arrow). The upper panel images are rendered immediately post HIFU ablation for each site. The TCM color is overlaid on the site as per ΔE value at the site
