Part of the Acoustical Imaging book series (ACIM, volume 15)


Tissue characterization of liver echographic scans was obtained using an optical-digital procedure of direct correlation between the unknown texture and a set of reference textures.

The method, tested on a selected group of static liver B-scans, gave a 90% accuracy. To date the search is being carried out by collecting and evaluating new cases of diffuse liver diseases: a set of 21 linear dynamic scans has been processed obtaining a 76.2% sensitivity in the correct recognition of a pathologic state. Considering only the cases with grade 1 fibrosis and/or grade 1 fatty infiltration a 69.2% sensitivity was achieved.
