Reduction of Speckle in Ultrasound B-Scans by Digital Processing Ultrasonic B-scans of regions of tissue whose inhomogeneities are small compared to the acoustic wavelength have a textured appearance with large fluctuations in echo amplitude; termed speckle. This texture pattern is caused by random in...

SpeckleFractional-order statisticsIt is necessary to identify speckled regions in ultrasound images to control adaptive speckle suppression algorithms, for tissue characterisation, and to estimate the elevational separation of B-scans by speckle decorrelation. Previous authors have proposed classification ...
Particularly, the HK distribution still allows characterizing tissues when the region of analysis belongs to the case of concentrated or denser media exhibiting fully developed speckle patterns in ultrasound B-scan [27]. This implies the HK parameter as a more suitable ultrasound imaging biomarker to...
