METHOD OF REGISTERING IMAGES, ALGORITHM FOR CARRYING OUT THE METHOD OF REGISTERING IMAGES, A PROGRAM FOR REGISTERING IMAGES USING THE SAID ALGORITHM AND A METHOD OF TREATING BIOMEDICAL IMAGES TO REDUCE IMAGING ARTEFACTS CAUSED BY OBJECT MOVEMENT

摘要

The invention provides for a method for registering biomedical images including an automatic trackable landmark selection step consisting in defining a pixel or voxel neighbourhood around each pixel or voxel of the first image or first set of cross-sectional images; for each target pixel or voxel determining one or more characteristic parameters which are calculated as a function of the parameters describing the appearance of the said target pixel or voxel and of each or a part of the pixels or voxels of the window and as a function of one or more characteristic parameters of either the numerical matrix or of a transformation of the said numerical matrix representing the pixels or voxels of the said window. The pixels or voxels coinciding with validly trackable landmarks are determined as a function of the said characteristic parameters of the target pixels or voxels.
