Thank you very much and, you know, I wanna remind you that after…after the meeting these images and slides will be on the…on the web, so that I can feel free to go relatively quickly. But I wanna try and survey a very large area and, basically, many of us are gonna be talking about computer aided surgery and in particularly, some of the image guided interventions, which might be properly classified as one aspect of computer aided surgery. The purpose for this talk is really to survey a lot of these technologies, so I borrowed heavily on the work of many outstanding groups and they’re acknowledged at the end. And I would like to leave you with some idea of the applications of these kinds of interventions. The motivations for this are many. We would like to improve on current practice and then, open the opportunity to develop therapies which couldn’t be done without this and to do it in a minimally, or less invasive, fashion. So, this is the outline of my talk and I’ll get through as much of this as I can in the few minutes that are available. Talk a little bit about the general topic, then to show you a vertebroplasty, say a few words on CT fluoro, and then, some other types of biopsy procedures and robotic procedures that are done under image guidance. First of all, I think it’s worthwhile to have a definition and the definition is, of course, for a GI would be that you use images and these, typically, would be real time, although, not necessarily. ...
