The backscattered ultrasonic echo from tissue can be described in terms of Rayleigh
distribution or K distribution. Even though both generalized K distribution and homodyned K …

Tissues exhibiting quasi-periodic structures can be modeled as a collection of diffuse
scatterers and coherent scatterers. The mean scatterer spacing (MSS) of coherent and quasi …

Since the late 1970s, the speckle interference patterns ubiquitous in pulse-echo ultrasound
images have been used to characterize sub-resolution tissue structure. During this time, new …

Fully developed speckle patterns observed in coherent imagery are characterized by a
Rayleigh-distributed envelope amplitude. Non-Rayleigh distributions are observed in many …

Mean scatterer spacing (MSS) holds particular promise for the detection of changes in
quasiperiodic tissue microstructures such as may occur during development of disease in …

There is a strong interest in finding out which statistical model is the most appropriate for
describing the envelope of the backscattered ultrasonic echoes from different types of …

Very little is known about the blood backscattering behavior and signal statistics following
flow stoppage at frequencies higher than 10 MHz. Measurements of the radio frequency (rf) …

Optimization of efficiency in hyperthermia requires a precise and non-invasive estimation of
internal distribution of temperature. Although there are several research trends for ultrasonic …

The homodyned K-distribution and the K-distribution, viewed as a special case, as well as
the Rayleigh and the Rice distributions, viewed as limit cases, are discussed in the context …

Diagnostic ultrasonography has its well-established role in medicine. Nevertheless, the
quantitative characterisation of biological tissues by ultrasound (US) is still a main topic of …
