Spatially varying 2d image processing based on 3d image data

Abstract

It is described a 2D image processing of an object under examination in particular for enhancing the visualization of an image composition between the 2D image and a 3D image. Thereby, (a) a first dataset representing a 3D image of the object is acquired, (b) a second dataset representing the 2D image of the object is acquired, (c) the first dataset and the second dataset are registered and (d) the 2D image is processed. Thereby, based on image information of the 3D image, within the 2D image processing there is at least identified a first region (231, 331) and a second region being spatially different from the first region (231, 331), and the first region (231, 331) and the second region are processed in a different manner. An improved visibility for 3D roadmapping can be achieved by means of image coloring and other 2D-image processing procedures such as contrast/brightness settings, edge-enhancement, noise reduction and feature extraction, wherein these 2D image processing is diversified separately for multiple regions of pixels, such as inside and outside a vessel lumen (231, 331).
