In conventional ultrasound imaging system, the design of dynamic filter needs the center frequency of the near field and far field first, which were calculated using the linear sound field model. Then the frequencies are used to determine the factors of the dynamic filter for every section of the echo.

By using the generalized central limit theorem, the heavy-tailed distributions (heavy-tailed Rayleigh distribution for amplitude image and heavy-tailed exponential distribution for intensity image) are obtained from the symmetric stable distributions of real and imaginary parts of echoes. Taking the heavy-tailed Rayleigh distribution as an example, the algebraic tails of heavy-tailed distributions are explained as well as the statistics of sharp peak and heavy tail.
