Today I had my first SBRT treatment in earnest and it went very smoothly.
I arrived on time and the first step was drinking a cup of water and then waiting 45 minutes for it to fill up my bladder.
I changed into the gown and was then led into the room with SBRT machine. I was placed on the flat table just like during the simulation, the technicians moved me into place, and then the "mold" was placed over my mid-section and secured firmly.
About 10 minutes was spent getting the machine ready, and then the announcement came over the speakers that the treatment was going to begin. It all was very much akin to an MRI machine experience except that the machine was actually moving around you. I basically just closed my eyes and listened to the music being piped in because seeing the machine move around sometimes did give me the feeling that I was moving but the machine was staying still!
To me, it felt like the actual treatment part of the procedure took about 10 minutes... 15 minutes, tops. I didn't feel anything, of course, and I had no trouble getting dressed and heading right home.
It's only been about four hours since my treatment, so I'm not feeling any side effects or such just yet. As that progresses, I'll follow up with more info in the "reply/comments" section down below.
