Abstract

In this paper, a method is proposed to detect the endocardial contour of the left ventricle using the Hough transform with a weighted model and edge information from the 2D echocardiogram. The implementation of this method is as follows: first, an approximate model detection algorithm was implemented in order to detect the approximate endocardium model and the model center, then we constructed a weighted model with the detected model. Next, we found automatically the cavity center of the left ventricle performing the Hough transform which used the weighted model, and then we detected the endocardial contour using weighted model and edge image.

본 논문에서는 2D 심초음파영상으로 부터 가중모델을 검출하고 이 모델로써 Hough변환을 수행하여 좌심실의 심내벽윤곽을 검출하는 방법을 제안하였다. 제안된 방법의 수행은 다음과 같이 크게 두단계로 나누어진다. 첫번째 단계에서는 근사적인 심내벽 모델과 모델의 중심을 검출하기 위하여 근사모델 검출 알고리듬이 수행되고 그런다음, 검출된 모델로써 가중모델을 구성한다. 두번째 단계에서는 가중모델과 에지영상을 이용한 Hough변환을 수행하므로써 좌심실 동공의 중심을 자동적으로 찾은 다음, 가중모델, 에지영상 및 동공의 중심과 같은 지식을 이용하여 심내벽 윤곽을 검출하였다.
