Abstract
An image guided surgical procedure using an improved registration of pre-operative volumetric scan data is described. Volumetric scan data, acquired before surgery, is registered with respect to the patient and used to construct a volumetric perspective image of the surgical site. The improved registration of the volumetric scan data can be accomplished by generating a pattern of light on the patient's surface by moving a laser beam over the surgical site. The pattern of light is recorded by at least two cameras from different known fixed positions, digitized and used to form a laser reconstruction of the patient surface. This digital surface can then aligned with the volumetric scan data forming an improved volumetric perspective image of the surgical site.
