1. A method, comprising:
- receiving first emplacement data associated with a first device tracker associated with a first medical device;
receiving second emplacement data associated with a second device tracker associated with a second medical device;
determining emplacement of a virtual 3D rendering of the first medical device with respect to a point-of-view location based at least in part on the first emplacement data;
determining emplacement of an image region with respect to the point-of-view location based at least in part on the second emplacement data;
determining an intersection of an axis associated with the virtual 3D rendering of the first medical device and at least a portion of the image region based at least in part on the determined emplacement of the virtual 3D rendering of the first medical device and the determined emplacement of the image region;
determining an intersection indicator based at least in part on the determined intersection, a variance parameter of the first device tracker, and an orientation angle of the virtual 3D rendering of the first medical device with respect to the image region; and
causing one or more displays to concurrently display;
a perspective view of at least a portion of the virtual 3D rendering of the first medical device in a virtual 3D space based at least in part on the determined emplacement of the virtual 3D rendering of the first medical device,a perspective view of at least a portion of the image region based at least in part on the determined emplacement of the image region, andthe intersection indicator, wherein an area of the intersection indicator increases in proportion to a decrease in the orientation angle.

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 indicator in a virtual 3D space.

2. A method, comprising:
-
receiving first emplacement data associated with a first medical device; receiving second emplacement data associated with a second medical device; determining emplacement of a first virtual medical device with respect to a point- of-view location based at least in part on the first emplacement data; determining emplacement of an image region with respect to a point-of-view location based at least in part on the second emplacement data; determining an intersection based at least in part on the first emplacement data and the second emplacement data; and causing one or more displays to concurrently display; a perspective view of at least a portion of the virtual medical device in a virtual 3D space based at least in part on the determined position and orientation of the virtual medical device, a perspective view of at least a portion of the image region, and an intersection indicator based at least in part on the determined intersection and an orientation angle of the first virtual medical device with respect to the image region, wherein a size of the intersection indicator increases in proportion to an increased difference between the determined orientation angle and a threshold angle. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15)

17. A system, comprising
one or more processors communicatively coupled with one or more displays; - and
a non-transitory computer-readable storage medium storing computer-executable instructions that when executed by the one or more processors cause the one or more processors to; receive first emplacement data associated with a first medical device; receive second emplacement data associated with a second medical device; determine emplacement of a first virtual medical device with respect to a point-of-view location based at least in part on the first emplacement data; determine emplacement of an image region with respect to a point-of-view location based at least in part on the second emplacement data; determine an intersection based at least in part on the first emplacement data and the second emplacement data; and cause one or more displays to concurrently display; a perspective view of at least a portion of the virtual medical device in a virtual 3D space based at least in part on the determined position and orientation of the virtual medical device, a perspective view of at least a portion of the image region, and an intersection indicator based at least in part on the determined intersection and an orientation angle of the first virtual medical device with respect to the image, wherein a size of the intersection indicator increases in proportion to an increased difference between the determined orientation angle and a threshold angle. - View Dependent Claims (18, 19, 20)
