These are our latest and best medical techniques, yet thousands of people avoid such life-saving procedures out of fear of radiation. We should be thankful, of course, that microsurgical techniques have also improved greatly in the last decade. Still, as one neurosurgeon has put it, in terms of patient discomfort radiosurgery versus microsurgery is somewhat analogous to comparing a haircut to a root canal. I chose the haircut. Most of us a average by definition.
Microsurgery is a very very skilled craft.
By contrast, GK or FSR are routines which are largely mechanised and very repeatable. You know, I like to use car analogies in discussing treatment. Well, let's call the Surgeons hand builders of cars, and the radiosurgeons the mass production companies. So at best, you go on reputation, but unfortunately like the rest of us humans, even the best surgeon can have an off day. When you work to the tolerances and under the strains that these guys do, even a very minor thing will reflect in the standard of your work.
