1. A method of determining the multi-dimensional topology of a substance within a volume, the method comprising the steps of:

  • a) acquiring a set of relative density values for the volume, each value for a given location within the volume;

    b) interpolating a set of functions to generate a continuous relative density for the volume;

    c) identifying critical points of the continuous relative density by using an eigenvector following method;

    d) associating critical points with one another by following a gradient path of the continuous relative density between the critical points; and

    e) generating a representation of the topology according to the associated critical points.
