We have a CyberKnife here in Ottawa. As you said, it's a robotic unit that gives focused beams of radiation to small targets in the body. In fact, that technique has been a major step forward in the treatment of stage one lung cancer in those patients who, for whatever reason, cannot have an operation.
The answer to your question is that this form of radiation or that technique can be delivered with other machines. In fact, even though we have a CyberKnife in Ottawa, of the 170 patients we treated in the last calendar year with that technique, we actually did not treat them on a CyberKnife. We treated them on another technology that does a very nice job for lung cancer.
