Another question related to the last post. In the transform denoted by equation A1, M_s and M_q are defined as matrices that map a voxel-coordinate vector into a mm-coordinate vector and that these map the geometric center of spaces S and Q to mm-coordinate (0,0,0). Is is correct to say that the mapping of a voxel coordinate to a mm-coordinate is simply the distance of a given voxel from the geometric center given the voxel dimensions?
Thanks,
Colin
