1. A method for adaptive non-rigid registration of multiple measurement modes of a target body, comprising the steps of:

  • receiving first data comprising a first plurality of measured values each associated with a plurality of coordinate values for spatial or temporal dimensions based on a first measurement mode of a target body;

    receiving second data comprising a second plurality of measured values each associated with a plurality of coordinate values for spatial or temporal dimensions based on a different second measurement mode of the target body;

    determining a linear transformation to maximize a coarse scale similarity measure between the first data and the second data;

    sub-dividing the second data into a plurality of sub-regions each comprising a spatially or temporally contiguous subset of the second data;

    determining a plurality of non-rigid transformations to maximize a fine scale similarity measure between the plurality of sub-regions and a plurality of corresponding portions of the first data wherein the non-rigid transformations include shear and at least one of compression or expansion; and

    transforming the plurality of coordinate values for each measured value of the second data based on the plurality of non-rigid transformations.
