1. A guidance system, comprising one or more processors, the guidance system configured to:
- receive emplacement data associated with a first emplacement sensor with respect to a first coordinate system;
receive emplacement data associated with a second emplacement sensor with respect to the first coordinate system;
receive emplacement data associated with a third emplacement sensor with respect to a second coordinate system, the third emplacement sensor associated with a head mounted display;
determine an emplacement of a first virtual medical device with respect to a third coordinate system based at least in part on the received emplacement data associated with the first emplacement sensor, an offset, and the received emplacement data associated with the third emplacement sensor;
determine an emplacement of a second virtual medical device with respect to the third coordinate system based at least in part on the received emplacement data associated with the second emplacement sensor, the offset, and the received emplacement data associated with the third emplacement sensor;
receive a real-time medical imaging stream associated with the second virtual medical device;
determine an emplacement of the real-time medical imaging stream with respect to the third coordinate system based at least in part on the received emplacement data associated with the second emplacement sensor, the offset, and the received emplacement data associated with the third emplacement sensor; and
cause a display of the head mounted display to display a 3D rendered view of a virtual 3D volume including;
a 3D rendering of at least a portion of the first virtual medical device based at least in part on the determined emplacement of the first virtual medical device,a 3D rendering of at least a portion of the second virtual medical device based at least in part on the determined emplacement of the second virtual medical device, anda 3D rendering of the real-time medical imaging stream based at least in part on the determined emplacement of the real-time medical imaging stream,wherein the 3D rendered view changes in relation to a change in the received emplacement data associated with the third emplacement sensor.

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.
