Abstract

Techniques of determining a spatial correspondence between a source imaging dataset - e.g., a Computed Tomography medical imaging dataset or a Magnetic Resonance Tomography medical imaging dataset - and a target imaging dataset using a point-matching algorithm are disclosed. In addition to similarity values between respective descriptors considered by the point-matching algorithm, a consistency of an output of the point-matching algorithm is additionally taken into account. This consistency is determined by forward-backward execution of the point-matching algorithm and then assessing a respective spatial distance or offset.
