Just wondering. I know we had a thread about that, but figured I'd start a new one for anyone who is actually undergoing the treatment.
Please relay your experiences.
I am still trying to find out if the initial mapping involves any invasive precedures (ie: catheters---UGH-- that's a bummer)

After this afternoon I'll be able to say that I've had it. My first treatment is today after work. As for the mapping, yes they use a cath, but I wouldn't let that scare you off from using the RapidArc. It's a brief discomfort in return for a significant return. It makes sense that they need to use a cath for mapping, so they can put contrast in the bladder and colon. They put different types of contrast in each to help differentiate them in the imaging (barium in the back, iodine in the front).

That thought is still a bummer.
I did call and they said maybe; some yes and some no. The doctor decides.
I think that's just doubletalk for yes but we don't want to tell you that now!
My next PSA will be 12/30 or thereabouts

I was at my radologist for a followup today and asked him about the Varian Rapid Arc. He has the Rapic Arc as well as some other machines in his practice. He uses the Rapid Arc for mostly neck and head cancers, but says it works well for prostate cancer, but perfers to use the Tomo machine for prostate cancer because he can better sculpture the beam to the irregular shape of the prostate. The bigest advantage of the Rapid Arc is to the radiologist as it is much faster and he can get much better patient throughput. For SRT, where there is no prostate and you are treating a general area just about any radiation would suffice and there is probably no advantage to one particular technology over another.
