ABSTRACT:
A method and a surgical guidance system (20) direct an instrument to a target (40) located inside a patient (22). The surgical guidance system (20) includes a fixation frame (28), a first arc member (36), a second arc member (38), and first (78) and second (84) electromagnetic (EM) radiative sources. The first arc member (36) and the second arc member (38) are adjustably coupled to rotate about a common axis (48) and are adjusted in response to a target address and at least three marker addresses so that the target (40) is located at the center point of a virtual sphere defined by the arc members. A first electromagnetic (EM) radiative beam (80) and a second electromagnetic (EM) radiative beam (86) are projected from the system (20) and intersect at a line. The line forms a trajectory (146) along which an instrument can be directed to the target (40).
