Loupe display

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.

         28 . A method of presenting virtual content to a user of a head mounted display, the method comprising:
 receiving first emplacement data associated with a first emplacement sensor with respect to a first coordinate system;   receiving second emplacement data associated with a second emplacement sensor with respect to a second coordinate system, the second emplacement sensor associated with a head mounted display;   determining an emplacement of a medical device with respect to a third coordinate system based at least in part on the received first emplacement data, the received second emplacement data, and an offset; and   causing a display to display a rendering of at least a portion of the medical device based at least in part on the determined emplacement of the medical device, wherein the rendering of the at least a portion of the medical device varies in relation to a change in the received second emplacement data.   
     
     
         29 . The method of  claim 28 , wherein the second emplacement sensor is associated with a real medical device. 
     
     
         30 . The method of  claim 28 , wherein the offset is configured to allow a viewer of the display to simultaneously view at least a portion of the medical device on the display and at least one of at least a portion of the real medical device above the display or at least a portion of the real medical device below the display. 
     
     
         31 . The method of  claim 28 , further comprising:
 receiving third emplacement data associated with a third emplacement sensor with respect to the first coordinate system;   determining an emplacement of a second medical device with respect to the third coordinate system based at least in part on the received second emplacement data, the received third emplacement data, and the offset; and   causing the display to display a rendering of at least a portion of the second medical device based at least in part on the determined emplacement of the second medical device, wherein the rendering of the at least a portion of the second medical device varies in relation to a change in the received third emplacement data.
