Abstract
A system (100) is provided for determining a transformation between different coordinate systems associated with different medical data. In determining the transformation, the system (100) makes use of a third set of anatomical landmarks (040) defined in a reference coordinate system to match a first set of anatomical landmarks (010) defined in a first coordinate system to a second set of anatomical landmarks (020) defined in a second coordinate system. Effectively, the third set of anatomical landmarks is used as an intermediary in obtaining the transformation between both input sets of coordinate systems. As the third set of anatomical landmarks includes the anatomical landmarks of both input sets, it is not needed for both input sets to be identical or even to overlap. Rather, even in case both input sets are entirely disjunct, i.e., not-overlapping, it is still possible to determine the transformation between the different coordinate systems.
