In this paper, an approach for the extraction of quantitative parameters from multi-directional ultrasound echo signal data for the differentiation and characterization of specular reflections and diffuse backscattering is presented and evaluated. Spatially resolved, tissue-characterizing parametric images are calculated by analyzing the envelope of echo signals from different insonation angles. Frames...
Ultrasound spatial compounding has been proven to successfully improve the image contrast, to achieve a more isotropic resolution and to reduce imaging artifacts in comparison with conventional B-mode imaging. For high- frequency ultrasound (HFUS) imaging of skin, usually linear scans only are performed perpendicularly to the axial direction of sound propagation. In this paper the potential of HFUS...
