Claim One:
1. A method for registration of medical images, the method comprising: receiving a 2D image acquired with a medical 2D imaging device under a first view direction; filtering the 2D image, such that high frequency components of the 2D image are emphasized with respect to low frequency components of the 2D image; receiving a 3D image acquired with a medical 3D imaging device; generating a 2D projection image from the 3D image, wherein the 2D projection image is generated with a second view direction; overlaying the filtered 2D image and the 2D projection image; providing functionality for changing the second view direction, such that the 2D projection image is registered with the filtered 2D image, wherein filtering the 2D image comprises a multi-resolution analysis, in which the 2D image is decomposed into a set of component images, each component image containing an image content of the 2D image relating to a specific resolution, wherein a brightness and/or a contrast of the at least one component image is adjusted for emphasizing and/or suppressing frequency components.
