Development of a new diagnostic system for human liver diseases based on conventional ultrasonic diagnostic equipment

In this paper, the authors present the experimental results of using a quan titative ultrasonic diagnosis technique for human liver diseases using the fractal dimension (FD) of the shape of the power spectra (PS) of RF signals . We have developed an experimental system based on a conventional ultrason ic diagnostic system. As a result. we show that normal livers, fatty livers and liver cirrhosis can be identified using the FD values.
