Abstract

In this paper, we propose a novel method to extract muscle area from lumbar ultrasonographic image. The muscle area resided in lumbar area can be defined as the area between thoracic vertebra and subcutaneous fat area. A modified 4-directional contour tracing algorithm is designed to detect the boundaries and candidate areas are extracted and verified by the morphological characteristics of lumbar area. The experiment using 392 lumbar images verifies that the proposed method is sufficiently effective by showing over 94% accuracy in extraction.

본 논문에서는 요부 영상에서 근육을 추출하는 방법을 제안한다. 제안된 방법은 요부 초음파 영상에서 피하지방층과 등뼈 영역을 각각 분류하여 피하지방층의 하단 부분과 등뼈의 상단 부분의 경계선을 개선된 4방향 윤곽선 추적 알고리즘을 적용하여 추출하고 이 두 경계선 내에 있는 영역을 요부의 근육 영역으로 추출한다. 본 연구에서 제안한 방법을 392개의 요부 초음파 영상에 적용하여 근육 영역을 추출한 결과, 제안된 방법은 94% 이상의 추출률을 보였다.
