Cyber knife question

I am going to consult with a radiation onc later this month to discuss having cyberknife done - I currently have 3 tumors in my brain wihich are all under 1cm and my onc says it would be a good idea- he thinks this procedure is more precise than the gamma- has anyone had it ? What to expect? We got this machine in our area just last Dec.Any input would be aprreciated. God Bless.
