Abstract
A system and method for providing image guidance for placement of one or more medical devices at a target location. The system receives emplacement information of medical devices within a predetermined area. The system calculates a viewing angle in a virtual 3D space of a plurality of virtual medical devices corresponding to the plurality of medical devices. The system also causes a display device to display the plurality of virtual medical devices based at least on the calculated viewing angle.
