1. A method for providing an image of a lung sample having an airway tree, the method comprising the steps of: a) recording images encoding motion data for the sample in terms of Cartesian coordinates; b) reconstructing a 2D or 3D motion field from the encoded motion data in the recorded images; c(i) segmenting an image of the airway tree of the lung sample; c(ii) associating segments of ends of the airway tree from step c(i) with regions of the 2D or 3D data motion field; and c(iii) using the regions of the 2D or 3D motion field identified from step c(ii) to determine one or more parameters in one or more other segments of the segmented image; wherein steps a-c are automated.
