Abstract

An adaptive roadmapping device and method for examination of an object include providing pre-navigation image data representing part of the object being a vascular structure including an element of interest and having a tree-like structure with a plurality of sub-trees; generating a vessel representation based on the pre-navigation image data; acquiring live image data of the object; determining spatial relation of the pre-navigation image data and the live image data; analyzing the live image data by identifying and localizing the element in the live image data; determining a sub-tree in which the element is positioned, where the determining is based on the localization of the element and on the spatial relation; selecting a portion of the vascular structure based on the determined sub-tree; generating a combination of the live image data and an image of the selected portion of the vascular structure; and displaying the combination as a tailored roadmap.
