It certainly sounds attractive.... imagine you only need one treatment. The (single) radiation dose is big enough to kill the cells.
From what I glean cyberknife is good for well defined and (smallers) tumors while IMRT is for larger and more irregular tumors... Cyberknife could potentially be used for reirradiation (lower dose)
Anyway, here is some info for you:
