Abstract :
This paper describes an experimental evaluation of the statistical properties of microbubbles by the means of Nakagami probability distribution. The first and second harmonic images are used for statistical analysis of backscattered signals from saline with different concentration of microbubbles (SonoVue). There were no differences between the shape parameters m from Nakagami distribution obtained from the first and second harmonic images, which was confirmed by t-test (p<;0.001). The results also show the scattering conditions for each concentration described by the values of this shape parameter.
