“…Many statistical models have been investigated for describing the characteristics of the US speckle under different scattering conditions. These models range from the well-known Rayleigh model (one of the most commonly used model based on the assumption that a resolution cell contains a large number of scatterers) to a class of nonRayleigh models comprising of K-distribution, Weibull distribution, log-normal distribution and Nakagami distribution [18,[20][21][22]. Among these density functions, the Nakagami and K-distribution provides better overall statistical fit to the observed data over a broad range of scattering conditions [22].…”

“…Alternative distributions to Rayleigh have been proposed for situations not meeting the requirements of fully developed speckle, such as insufficient numbers of scatterers per resolution cell, or non random positioning. These include the Rician, Nakagami and K distributions (Shankar et al, 2001;Shankar, 1995;Smolíovái et al, 2004).…”

Temperature monitoring is essential for various medical treatments. In this work, we investigate the impact of temperature on backscattered ultrasound echo statistics during a high intensity focused ultrasound treatment. A tissue mimicking phantom was heated with a spherical ultrasonic transducer up to 56 • C in order to imitate tissue necrosis. During the heating, an imaging scanner was used to acquire backscattered echoes from the heated region. These data was then modeled with the homodyned K distribution. We found that the best temperature indicator can be obtained by combining two parameters of the model, namely the backscattered echo mean intensity and the effective number of scatterers per resolution cell. Next, ultrasonic thermometer was designed and used to create a map of the temperature induced within the tissue phantom during the treatment.
