Just like in the simulation and dry run, a therapist positioned me on the table, then fled the room. This time, though, the gantry did its thing. It started directly below the now-elevated table, made a high pitched humming noise for a few minutes, and then moved 15 or 20 degrees and did it again. When it had made a complete circle around me, the session was over. Less than 15 minutes. I can leave work, get the treatment, and be back at my desk all within 40 minutes.
I don't think I drank enough water this morning, though. I'll have to make sure I do that. Not that it makes any difference in what is experienced during the session, but over the course of treatments it should help reduce urinary irritation.
