Joe,
While the radiation focally given may be basically the 'same', the experience is VERY DIFFERENT.
Three times I had Linear Accelerator screwed on headframes, (more similar to the Gamma Knife) ,waiting all day from 7am to done at 6pm, with the headframe on, taking pain meds when the 'pin sites' became painful, trying to drink or eat anything with that huge frame on head, trying to 'rest' or get 'comfortable', getting the headframe removed being very painful in itself, the excruciating headache for two hrs after each of the three procedures........
Compared to CyberKnife. Less than an hour to make the mask. Seconds with hot mesh on face.
In at 10:30am, mask tightly fastened down on table, tight on face, an hour for multiple sites treated, out the door at noon. I did this twice, two days apart to address six brain mets.
So, for me personally... I would never say that CyberKnife and Gamma Knife are basically the same procedure. Not even close.
