Medical imaging system and method for providing an image representation supporting accurate guidance of an intervention device in a vessel intervention procedure
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).
