肝臟纖維化之非侵入式超音波檢測裝置

A non-invasive ultrasound detection device for liver fibrosis and method thereof are disclosed. The method comprises the steps of: creating a discriminant function of several parameters, each with a weight obtained by LDA, based on a database; and determining the degree of liver fibrosis by comparing a reference value and a numerical value calculated from the discriminant function. The parameters represent different probability distribution function capable of identifying liver fibrosis or fatty liver. In the step of creating a discriminant function, the database provides the processed data based on numerous ultrasound images of patents’ livers for LDA. In the step of determining the degree of liver fibrosis, the processed data based on ultrasound images of a person’s liver are obtained for further calculation of the numerical value. The processed data include an average value for each probability distribution function within an area corresponding to a liver.
