1. An imaging method comprising:
creating a vessel image, which maps a vessel structure of an object to be imaged, and also a device image, which maps a device arranged in the object, by an imaging apparatus; and
applying, by a processor, at least one filter algorithm to the device image, resulting in a filtered device image, wherein the at least one filter algorithm includes a local contrast enhancement, wherein the local contrast enhancement comprises creating, by the processor in the applying: an unsharpened input image based on an input image dependent on the device image, a contrast image created by subtraction of the unsharpened input image from the input image, and an enhanced-contrast image created by overlaying of the input image with the contrast image or with an image dependent on the contrast image; and
creating, by the processor, an overlaying image by overlaying of the vessel image with the filtered device image.
