Technique for Visualization of Anisotropy of Biomedical Tissue by Shear Wave Acoustic Microscopy
The motivation for this work is the improvement in discrimination between anomalous biological tissue vis-à-vis normal tissue. When ultrasonically visualizing tissue surrounding a cancerous portion it is useful for medical diagnosis when the portion has a different contrast in the image. The cancer tends to grow with its own direction typically different from normal tissue. Therefore, if we could ultrasonically visualize both isotropy and anisotropy of the tissue, the cancerous tissue may be discriminated from the normal tissue.
