The Sonablate 500 TCM monitor display during the whole gland ablation of prostate tissue. The lower (reference) and upper (real-time) panels are transverse and sagittal ultrasound images of the prostate (pre and post HIFU) for each ablative site, respectively. The upper panel images are marked with transducer focal zone and selected tissue ablative sites. The ΔE calculation is computed after each HIFU exposure and a green, yellow or orange color is overlaid on the ablated site as per Table 1 color scheme
