| Research Abstract |
The aim of this research is the realization of a quantitative diagnosis method of liver diseases using ultrasound. As a result of measuring and analyzing of physical and acoustic characteristics of rat livers using ultrasonic microscope systems, the correlation of tissue properties and various physical properties was confirmed. Moreover, the detection of the echo signal from fat and fiber tissues became possible, when some signal processing methods were given to echo data acquired at computer simulations, tissue mimicking phantoms, and clinical data sets using ultrasonic diagnostic equipment. The qualitative evaluation of the tissues in diffuse liver disease is actualized by fusion of both results.
