Contrast-enhanced ultrasound (CEUS) is a sensitive imaging technique to evaluate blood perfusion and tissue vascularity, whose quantification can assist in characterizing different perfusion patterns, e.g. in cancer or in arthritis. The perfusion parameters are estimated by fitting non-linear parametric models to experimental data, usually through the optimization of non-linear least squares, maximum likelihood, free energy or other methods that evaluate the adherence of a model adherence to the data. However, low signal-to-noise ratio and the nonlinearity of the model make the parameter estimation difficult.
