ABSTRACT:
A method and apparatus for its practice are provided of differentiating at least one component of a heterogeneous sample from other component(s) using harmonic resonance imaging and of obtaining information regarding the sample from the differentiation. In a preferred embodiment, an image is created of a property of a harmonic or a combination of a harmonics producing a response having a contrast factor between the sample's constituent components. The desired harmonic(s) can be identified either in a preliminary data acquisition procedure on the sample or, if the sample's constituent components are known in advance, predetermined. The desired harnonic(s) may be identified directly by the user or automatically through, e.g., pattern recognition. A compositional map may then be generated and displayed and/or additional information about the sample may be obtained.
