"The spatial Bessel filters are studied for their ability to reduce ultrasonic speckle and enhance the boundaries of regions of interest (1101) in medical B-mode images. Using the concept of the heterogeneity index, a new parameter defined to provide a quantitative measure of the edge visibility," scientists writing in the journal IEEE Transactions on Ultrasonics Ferroelectrics and Frequency Control report.
"It is hypothesized that this edge visibility parameter will be almost equal to unity if the ROI does not contain a boundary and greater than unity when the ROI contains a boundary. Analyses of 2 computer-synthesized images containing speckle and B-mode images ...
