The rectal probe looks much larger than the standard biopsy/ultrasound probe. Is that why the spinal is required?
Actually the probe is not much larger. The procedure is completed under spinal anesthesia which is required so the patient remains comfortable and still through the two hour treatment. This is very important. When the machine detects any movement, treatment stops immediately. This is one of the many safety mechanisms offered with Ablatherm HIFU as programming and treatment are very precise. Another safety feature is that the treatment probe is constantly measuring the distance between the treatment probe and the rectal wall.
