METHODS, SYSTEMS AND COMPUTER PROGRAM PRODUCTS FOR POSITIONING A GUIDANCE APPARATUS RELATIVE TO A PATIENT
First Claim
1. A method for positioning a guide device for placement of an interventional object in a body, the guide device having a guide axis, the method comprising:
- determining a target point in the body and a reference point, wherein the target point and the reference point define a planned trajectory line (PTL) extending through each;
determining a visualization plane, wherein the PTL intersects the visualization plane at a sighting point;
mounting the guide device relative to the body to move with respect to the PTL, wherein the guide device does not intersect the visualization plane;
determining a point of intersection (GPP) between the guide axis and the visualization plane; and
aligning the GPP with the sighting point in the visualization plane.

Abstract
A method for positioning a guide device for placement of an interventional object in a body, the guide device having a guide axis, includes: determining a target point in the body and a reference point, wherein the target point and the reference point define a planned trajectory line (PTL) extending through each; determining a visualization plane, wherein the PTL intersects the visualization plane at a sighting point; mounting the guide device relative to the body to move with respect to the PTL, wherein the guide device does not intersect the visualization plane; determining a point of intersection (GPP) between the guide axis and the visualization plane; and aligning the GPP with the sighting point in the visualization plane.

7. A method for positioning a guide device for placement of an interventional object in a body, the guide device having a guide axis, the method comprising:
-
determining a target point in the body and a pivot point, wherein the target point and the pivot point define a planned trajectory line (PTL) extending through each; determining a visualization plane, wherein the PTL intersects the visualization plane at a sighting point, and wherein the sighting point is located on a segment of the PTL on a side of the pivot point proximate the target point; mounting the guide device relative to the body to pivot about the pivot point with respect to the PTL; determining a point of intersection (GPP) between the guide axis and the visualization plane; and aligning the GPP with the sighting point in the visualization plane.
