Rician inverse Gaussian model of scattering in ultrasound contrast media
Original language description
A statistical analysis of 1st and 2nd harmonic echoes backscattered from contrast media using Rician inverse Gaussian (RiIG) envelope model is described. Knowledge of statistics of the scattered signal may contribute to perfusion analysis. A range of ultrasound contrast agent (UCA) concentrations is examined. The RiIG distribution was fitted to image histograms, using Matlab Global optimization toolbox. Influence of simulated attenuation was also tested. Analysis of resulting RiIG distribution parameters shows that while its parameters alpha and beta do not follow any properties of the changing concentration, parameter delta shows logarithmic dependence on concentration in range of 3.125 - 50 mg/l. Taking into account simulated attenuation, we observedthat the range and shape of the dependency remain stable, although the actual range of parameter delta decreases with increasing attenuation. This analysis contributes to our previous results, where the Nakagami distribution showed simil
