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.
