Original Abstract

Recent developments saw Nakagami and extended Nakagami distributions being used for extracting useful information about ultrasound scenes by matching local histograms from envelope of radiofrequency signals. This information is conveyed by distribution parameters values. On the other hand, in research literature, new distributions or their extensions are proposed mostly on basis of quality of local histogram match in LMS sense. This measure is not linked in any way to significance of information contained in parameters of these distributions, though. As is shown here, in the context of contrast imaging, the Extended Nakagami distribution significantly improves neither quality of fit, nor information about local area, despite the additional parameter.
