    摘要: The present invention relates to visualizing information of an object. In order to provide spatial information and in addition situation specific data to the user while ensuring an effective perceptibility, a method (110) is provided comprising the steps of: a) providing (112) pre-navigation data (114) of a region of interest of an object (22); wherein the pre-navigation data comprises spatial geometrical data (116) and a functional parameter surface (118) in correspondence to the spatial geometrical data; b) acquiring (120) live image data (122) of the region of interest; c) detecting (124) an element (126) in the live image data; d) determining (128) spatial relation (130) of the pre-navigation data and the live image data; e) determining (132)the position (134) of the detected element in the spatial geometrical data, which determining is based on the spatial relation, and computing (136) a predetermined related point of location (138) on the functional parameter surface; f) generating (140) a combination (142) of a simplified surface representation (144) of the region of interest, which simplified surface representation is based on a visualization of the functional parameter surface, and a marker (146) indicating the computed predetermined related point of location; and g) displaying (148) the combination as navigation guidance (150).
