Claim One:
1. A method for facilitating a diagnostic or surgical procedure involving a subsurface target site in a patient, comprising (a) acquiring volumetric scan data of the target site, (b) moving a medical instrument to a selected orientation with respect to the patient target site; (c) determining the orientation of the medical instrument with respect to the patient target site; (d) selecting a field-of-view angle, (e) constructing from the volumetric scan data, a volumetric perspective image of the target site, as seen from the orientation of the medical instrument, at the selected field-of-view angle, and (f) displaying said perspective image to a person manipulating the instrument, in real time, allowing the person to visualize subsurface target structure at the selected field-of-view angle, as the medical instrument is moved with respect to the patient target site.
