Abstract:
1. A method for elastic registration of multiple scans of internal properties of a body, comprising the steps of: receiving control point transformation data that indicates a vector φ of values for transform parameters for each control point of a plurality of control points that correspond to scan elements in a reference scan, wherein determining a plurality of subsets of contiguous scan elements in the reference scan, wherein each subset of contiguous scan elements is associated with only one control point; determining on a processor an output vector v of values for transform parameters for each scan element in a first subset of scan elements of the reference scan, including the steps of after determining the output vector v of values for each scan element in the first subset, then determining on a processor the output vector v of values for each scan element in a different second subset of scan elements of the reference scan, wherein B(n) is a well known function for contributions at an arbitrary point from a control point at a normalized distance n=d/s where d is distance from the control point to the arbitrary point and s is separation of adjacent control points that straddle the arbitrary point.
