What is HIFU and Sonablate HIFU?
Tissue Change Monitoring (TCM)
TCM works by sending a radiofrequency (RF) signal to the treatment site prior to the delivery of HIFU.
Each treatment site is 3x3x12 mms high. Another signal is sent immediately after that segment has been treated.
TCM calculates the change in the tissue, depicted by a color. If the color is orange or yellow that signifies to the surgeon that the required temperature to ablate (Kill) the tissue has been achieved. If that color is not seen (green or gray), then the operator has the ability to retreat that area, before moving on to another zone of the prostate.
TCM quantifies tissue changes based on a comparison of radio frequency (RF) ultrasound pulse-echo signals at each treatment site.
