Abstract

A registration aid for medical images obtained from an examination subject respectively with different imaging modalities at separated points in time, has a carrier adapted to be reproducibly applied to an examination subject at separated points in time at a substantially identical position on the examination subject at each of the separated points in time, and at least one landmark provider carried by the carrier, the landmark provider providing a first landmark visible in a first of the imaging modalities and a second landmark, different from the first landmark, visible in a second of the imaging modalities. The landmark provider provides the first and second landmarks with a fixed spatial relation relative to each other to allow contents of an image obtained with the first of the imaging modalities to be brought into registration with contents of an image obtained with the second of the imaging modalities, with the carrier being applied to the examination subject while each of the images is obtained.
