MEDICAL IMAGING METHOD IN WHICH VIEWS CORRESPONDING TO 3D IMAGES ARE SUPERIMPOSED OVER 2D IMAGES

摘要

A method using an imaging device to define an acquisition geometry for 2D images of an observation region, a region for which there exists a 3D representation. 2D views of the 3D representation can be determined following the acquisition geometry of the imaging device for a plurality of viewing points, so that each acquired 2D image can be superimposed with any of this plurality of views. As a variant, in the 3D representation two views are determined corresponding to the viewing point at which the eye is positioned at the formation plane of the acquired image (front view and corresponds to the 2D image) and to the viewing point at which the eye is positioned at the focal point of the projective geometry (back view which is opposite to the viewing point of the 2D image). These two views allow the generation of two images for superimposition over the acquired image, defining superimposition of the acquired image with a front view of the 3D representation of the observation region and superimposition of the acquired image with a back view of the 3D representation of the observation region.
