Abstract
A registration system (200) for use in connection with an image guided surgery system (10) is provided. It includes a medical diagnostic imaging apparatus (100) for collecting image data from a subject (310). An image data processor (130) reconstructs an image representation of the subject from the image data. An image projector (230) depicts the image representation on the subject (310). In a preferred embodiment, the image projector (230) depicts the image representation on the subject (310) such that registration between the subject (310) and the image representation is readily apparent. Preferably, the image projector (230) is a laser lightshow projector, a projection television, or a backlit liquid crystal display device. Optionally, a data processor (210) applies corrections to the image data such that surface contours of the subject (310) are accounted for when the image is projected onto the subject (310).
