Abstract:
1. A method for imaging of a sample, the method being automated and including: recording images from at least one projection angle and carrying out image pair cross-correlation analysis encoding velocity data tor the sample in terms of Cartesian coordinates to measure encoded parameters of: (i) velocity (u, v and w) against time opposite Cartesian co-ordinates (x, y and z), and (ii) a further physical parameter (p) chosen from the group comprising pressure or volume; and reconstructing, without first reconstructing 2D or 3D images, a 2D or 3D velocity field directly from the image pair cross-correlations from the analysis, the reconstructing including: (a) integrating the measurements to provide a single 3D velocity field; and (b) describing regional compliance in terms of derivatives defined by (δu/δx+δv/δy+δw/δz)/δp.
