Now you can see why Varian has been so hell-bent to confuse the investment community as to the capabilities of gantry-mounted, co-planer machines versus the robotically controlled, multi-planer CyberKnife.

From Accuray Introduces the CyberKnife(R) VSI(TM) System:

"'There is a tremendous need for the capabilities built into the new CyberKnife VSI,' said Dwight Heron, M.D., chairman of the Department of Radiation Oncology at UPMC Shadyside. 'Depending on each individual patient's case, we will now be able to better tailor care so that the right amount of radiation is delivered to the right place in the right time frame for each patient, all with the same accuracy for which the CyberKnife is known.'"

Translation: Now that CyberKnife’s motion tracking real-time continual image guidance and robotic mobility can be applied to both conventionally fractionated IMRT as well as radiosurgery, every gantry-mounted radiation sprayer is obsolete.

And since the new smaller footprint CyberKnife can fit in the same existing radiation vaults that now house obsolete Varian radiation sprayers, it’s time to move those antique, aged, obsolete, gantry-bound, deaf-dumb-and-blind Varian radiation sprayers into some museum somewhere.

Accuray is Mercedes. Varian is Oldsmobile.
