ABSTRACT:
A lesion localization system is disclosed which employs imaging visible members (926, 928), and manifested sets of imaging space coordinates to define a retrograde point (1004) that is colinear with a lesion (940) and a selected entry point (946) thereto. Retrograde and antegrade lasers (1014, 1015) are employed to use the retrograde point in guidance of a medical instrument to the lesion. The localization system avoids mechanical calibration of stereotactic frames and is simpler to operate.
