I have looked at thread topics back about 2 years and have seen no mention of this machine.
I assume is it is similar to the Cyber Knife. Instead of the gold seeds, it uses what they claim are improved Beacon Transponders that are implanted in the prostate. They allow the machine to detect slight movement in the prostate from the bladder or bowel filling. I did notice the table I was on move a few times. They claim this allows for a more precise placement of the radiation and a higher dose. I had no problems with the treatment, only the Eligarg injections later. See calypsomedical.com.
