1. A method for medical device navigation, the method comprising:
- determining an emplacement of a virtual medical device corresponding to a medical device, the medical device comprising a joint member having a joint member axis, a first limb member having a first axis, and a second limb member having a second axis that is different from the joint member axis and the first axis;
determining an emplacement of a medical image slice;
determining a first intersection between an image plane corresponding to the medical image slice and a trajectory of the first limb member along a drive path;
determining a second intersection between the image plane and a trajectory of the second limb member along the drive path; and
causing one or more displays to concurrently display, in a virtual 3D space, a perspective view of;
at least a portion of the medical image slice based at least in part on the determined emplacement of the medical image slice,a first intersection indicator corresponding to the first intersection, anda second intersection indicator corresponding to the second intersection.

Abstract
A system and method for providing image guidance for placement of one or more medical devices at a target location. The system can determine one or more intersections between a medical device and an image region based at least in part on first emplacement data and second emplacement data. Using the determined intersections, the system can cause one or more displays to display perspective views of image guidance cues, including an intersection ghost in a virtual 3D space.

8. A method for medical instrument navigation, the method comprising:
-
determining an emplacement of a medical display object; determining an emplacement of a plane-of-interest; determining an emplacement of a ghost medical display object based at least in part on the determined emplacement of the medical display object and the determined emplacement of the plane-of-interest; and causing one or more displays to concurrently display, in a virtual 3D space; at least a portion of the medical display object, and at least a portion of the ghost medical display object on the plane-of-interest. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A method for medical instrument navigation, the method comprising:
-
determining an emplacement of a virtual medical device corresponding to a medical device, the medical device comprising a joint member having a joint member axis, a first limb member having a first axis, and a second limb member having a second axis that is different from the joint member axis and the first axis; determining an emplacement of an affected region based at least in part on the determined emplacement of the virtual medical device; and causing one or more displays to display, in a virtual 3D space, a perspective view of at least one of; at least a portion of the affected region based at least in part on the determined emplacement of the virtual medical device, or an intersection indicator indicating an intersection between an image plane and a trajectory of the affected region along a drive path that is parallel to the joint member axis. - View Dependent Claims (17, 18, 19, 20, 21)

22. A computer system in communication with a display, the computer system comprising a computer processor and a non-transitory storage medium, wherein the computer system is configured to:
-
determine an emplacement of a virtual medical device corresponding to a medical device, the medical device comprising a joint member having a joint member axis, a first limb member having a first axis, and a second limb member having a second axis that is different from the joint member axis and the first axis; determine an emplacement of a medical image slice; determine a first intersection between an image plane corresponding to the medical image slice and a trajectory of the first limb member along a drive path; determine a second intersection between the image plane and a trajectory of the second limb member along the drive path; and cause the display to concurrently display, in a virtual 3D space, a perspective view of; at least a portion of the medical image slice based at least in part on the determined emplacement of the medical image slice, a first intersection indicator corresponding to the first intersection, and a second intersection indicator corresponding to the second intersection. - View Dependent Claims (23, 24, 25, 26, 27, 28)
