1. A medical image viewing device for navigation in X-ray imaging, comprising: a processor configured to receive an angiographic image of a region of interest of an object, to identify a suppression area for partial bone suppression within the angiographic image, and to identify and locally suppress bone structures in the angiographic image in the suppression area of the region of interest, while providing bone structures outside the suppression area, yet in the region of interest, to generate a partly-bone-suppressed image; and a display configured to display the partly-bone-suppressed image.
