Research groups worldwide are advancing the state of the art in several
kinds of image guided surgery: telesurgery in which surgeon and patient are
physically distant, endoscopic or minimally invasive "keyhole" surgery, and
stereotactic or robot-guided surgery. This talk will begin with
descriptions and some video of projects in each of the above areas, and
discussion of what the key problems seem to be.
Our group's work in stereotactic surgery is motivated by the amazing
capabilities of medical diagnostic imaging, and the on-screen surgical
planning that can be done on the resulting images. Imaging and planning
has outpaced the surgeon's ability to carry out his/her plans in the
operating room. Robot-guided stereotactic surgery offers coordination
between diagnostic images and surgical procedures. The result is more
accurate execution of preoperative surgical plans, and (often) less
invasive procedures.
We will also discuss our recent work in "coordinated fluoroscopy",
where fluoroscope and a robot are used for three-dimensional planning and
surgery, even without a CT scan.
