The design of the ultrasonic three-dimensional filter for the liver disease diagnosis
Tadashi Yamaguchi (Chiba Univ.), Hiroyuki Hachiya (Tokyo Inst. of Tech.) MI2008-67
Abstract (in Japanese) (See Japanese page) 
(in English) At present, percutaneous liver biopsy is the gold standard in assessing liver fibrosis such as hepatitis and cirrhosis, but there could be sampling error, and specimens might not represent the state of the whole liver accurately because only about 0.002% of the organ is sampled. In this research, we propose the three-dimensional fiber structure extraction echo filter to realize a quantitative ultrasonic diagnosis. The filter is designed based on a statistical theory, and it is possible to reduce the noise contained in a back scattered ultrasonic echo signal, and to visualize the structure of a fiber.
