System and method of measuring fat content in target organ and recording medium of recording fat content measuring program

Method of measuring a fat content from an ultrasonic section image of a liver including a blood vessel wall and blood, the method of measuring the fat content comprising the steps of:

• storing the ultrasonic section image of said liver such that each of pixels has gray level distribution;
• setting a target section and a comparative section in each of longitudinal section from the stored ultrasonic section image of said liver;
• obtaining representative gray level values of the target section and the comparative section in each of the longitudinal sections;
• and
• quantifying the fat content of the target section in a value relative to the representative gray level value of said comparative section.
