Abstract

The Nakagami distribution was proposed recently for modeling the echo fromtissue. In vivo breast data collected from patients with lesions were studied using this Nakagami model. Chi-square tests showed that the Nakagami distribution is a better fit to the envelope than the Rayleigh distribution. Two parameters, m (effective number) and a (effective cross section), associated with the Nakagami distribution were used for the classification of breast masses, Data frost 52 patients with breast masses/lesions were used inthe studies. Receiver operating characteristics (ROC) were calculated for the classification methods based on these two parameters. The results indicate that these parameters of the Nakagami distribution may be useful in classification of the breast abnormalities, The Nakagami distribution may be areasonable means to characterize the backscattered echo from breast tissues toward a goal of an automated scheme for separating benign and malignant breast masses.
