Method of quantitatively measuring fat content in target organ from ultrasound visual image

A method of quantitatively assessing fat content in a target organ from an ultrasound visual image, the method comprising:

• obtaining an ultrasound visual image of the target organ;
• setting a target region and comparative regions in the obtained image;
• measuring a representative gray level of the target region from a gray level distribution of pixels of the target region;
• measuring representative gray levels of the comparative regions from the gray level distribution of pixels of the comparative regions;
• quantifying the representative gray level of the target region as relative values with regard to the representative gray levels of the comparative regions;
• and
• assessing fat content corresponding to the quantified representative gray level of the target region, wherein said target region measuring includes:
• obtaining a distribution pattern of pixels of the target region;
• obtaining histogram distributions of the number of pixels with regard to gray levels of each pixel of the target region;
• and
• determining the gray level of one histogram of the histogram distributions as the representative gray level, and
• wherein the representative gray level of the target region is determined as a gray level of a histogram positioning at a point of inflection in the histogram distribution.
