Abstract(in English) | We have been developing a quantitative estimation method of liver fibrosis using multi-Rayleigh model to express a probability density function (PDF) of echo envelope from a fibrotic liver. In this paper, optimal input moments are obtained by evaluating the spread of estimated values in the fibrotic parameters’ space using simulated ultrasound B-mode image. We also evaluate estimation characteristics of fibrotic parameters. It is found that better estimation of model parameters than conventional one is possible by using the combination in complex spaces. |
