Abstract
For characterizing spatial-temporal dynamics of a medium (1) excitable for deformation, an elastic model of the medium is defined. The medium is imaged at consecutive points in time to obtain a series of images. Shifts of structures of the medium (1) between the images of the series are determined. A dynamic description of a temporal development of spatial deformations of a predefined elastic model of the medium (1) is adapted to match the shifts of the structures; and temporal developments of rate of deformation patterns in the medium (1) are identified from the dynamic description.
