Abstract
The present invention relates to a device and method for registration of two images. To increase the accuracy of the registration the device comprises an input unit (126) for receiving one or more pairs of negative landmarks, which are indicated in the two images, a pair comprising two negative landmarks, one in each image, which structures are not identical and should not be aligned by the registration. Further, a registration unit (128) is provided for performing a registration of the two images by determining a transformation for transforming at least one of the images for registering it with the other image and determining a spacing measure of the distance between a first landmark in the transformed image and a second landmark in the other image, wherein the transformation is determined such that the spacing measure for a first landmark and a second landmark of at least one pair of negative landmarks is above a first distance threshold, whereby the negative landmarks are taken into account in the registration but are not aligned by the registration.
