The H-scan is
based on a simplified framework for characterizing scattering behavior, and
visualizing the results as color-coding of the B-scan image.
The methodology
begins with a standard convolution model of pulse-echo formation from typical
situations, and then matches those results to the mathematics
of Gaussian Weighted Hermite Functions.
In this
framework, echoes can be classified as returning from specific categories of
scatterers, and these can be conveniently displayed as colors. Thus, some
information not evident in conventional grayscale pulse-echo images can be
visualized in the H-scan format.
