Claim 0:
1. An ultrasound-medical-diagnosis apparatus using semantic segmentation, comprising:
an ultrasound probe sensor configured to acquire an ultrasound image from a patient;
an ultrasound image edge detector configured to detect a plurality of edge components on the ultrasound image;
an ultrasound examination item selection button inputter configured to receive an input from a user to select an organ of interest to examine;
a semantic segmentation artificial intelligence network configured to perform labeling on each of a plurality of organs of the patient by using mutually different colors to detect a position of the organ of interest on the ultrasound image;
an interest organ label separator configured to generate an organ label image displayed by extracting and separating the organ of interest selected by the user from the plurality of organs;
an interest organ searcher comprising an organ edge detector configured to generate an organ edge image by detecting an edge component of the organ label image derived from a two-dimensional image of the organ of interest, an organ edge width enlarger configured to generate an organ edge image with enlarged edge width by enlarging an edge width of the edge component detected by the organ edge detector such that the edge component enlarges in a greater proportion than rest of the organ of interest, and an edge overlapping quantity calculator configured to calculate a number of overlapping edge pixels by comparing the edge component on the organ edge image and the edge component of the two-dimensional image with each other on two-dimensional spatial coordinates;
an interest organ presence determiner configured to determine whether the organ of interest is present at each pixel of the two-dimensional image using the number of overlapping edge pixels calculated by the edge overlapping quantity calculator;
an interest region image extractor configured to extract an interest region image from the two-dimensional image through space addressing on the ultrasound image for an organ of interest region or an ultrasound-medical-diagnosis interest region around the organ of interest region, upon the organ of interest being present on the ultrasound image; and
a disease level displayer configured to determine and display a disease type and a disease level of the organ of interest based on the interest region image.
