Accurate diagnosis of acute appendicitis is a difficult problem in practice especially if the patient is too young or pregnant women in that radiological test have high risk. Thus, ultrasonographic image analysis is a good way to reduce the difficulty. However, studies show that there are few reliable common predictors and the decision is usually made by medical expert's naked eye examination since there is yet a reliable software tools to use in decision making. In this paper, we propose a new intelligent method to extract appendix from abdomen ultrasonography as a basic building block of developing such intelligent tool for medical practitioners. Knowing that the appendix is located at the lower organ area below the bottom fascia line, we conduct a series of image processing techniques to find the fascia line correctly. And then we apply fuzzy binarization to the organ area in order to extract appendix accurately. The experiment verifies that this two-phase image analysis is effective in extracting appendix.
