Abstract

In this paper, we propose a novel method to extract appendix from ultrasound image automatically to avoid such subjectivity issue. In the process, we apply a series of image processing algorithms such as Ends_in search stretching for emphasizing brightness contrast and binarization, region labelling, and cubic spline interpolation for extracting lower bound fasicia line that is the base of extracting the appendix. 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 ART2 algorithm to the organ area in order to extract appendix accurately. Through experiment, the effectiveness of the proposed method is verified based on the field experts' evaluations.

본 논문에서는 복부 초음파 영상에서 충수를 추출하는 방법을 제안한다. 제안된 충수 추출 방법은 복부 초음파 영상에서 명암 대비를 강조하기 위해 Ends_in Search Stretching 기법을 적용하고, Max-Min 이진화, 영역 레이블링, 잡음제거, Cubic Spline 보간법을 적용하여 복부 근육의 하단 근막 부분을 추출한다. 그리고 초음파 영상에서 추출된 근막 영역을 제거한 후, ART2 알고리즘을 적용하여 충수를 추출한다. 제안된 방법을 초음파 영상에 적용한 결과, 제안된 충수 추출 방법이 효율적으로 충수가 추출되는 것을 영상의학과 전문의를 통하여 확인하였다.
