Abstract
A method for augmented reality navigation of a medical intervention includes providing a stereoscopic head mounted display, the display including a pair of stereo viewing cameras, at least one tracking camera, and a stereoscopic guidance display. During a medical intervention on a patient, the patient's body pose is determined from a rigid body transformation between the tracking camera and frame markers on the scanning table, and the pose of an intervention instrument with respect to the table is determined. A visual representation of the patient overlaid with an image of the intervention target, the instrument, and a path for guiding the instrument to perform said medical intervention is displayed in the stereoscopic guidance display.
