Abstract

In this paper, a CORBA-based collaborative medical image analysis and visualization system, which provides high accessibility and usability of the system for the users on distributed environment is introduced. The system allows us to manage datasets and manipulates medical images such as segmentation and volume visualization of computed geometry from biomedical images in distributed environments. Using Bayesian classification technique and an active contour model the system provides classification results of medical images or boundary information of specific tissue. Based on such information, the system can create real time 3D volume model from medical imagery. Moreover, the developed system supports collaborative work among multiple users using broadcasting and synchronization mechanisms. Since the system is developed using Java and CORBA, which provide distributed programming, the remote clients can access server objects via method invocation, without knowing where the distributed objects reside or what operating system it executes on.

본 논문에서는 분산환경에서 사용자들에게 효과적인 접근성과 사용성을 제공하는 코바기반 협업 지일 의료영상 분석 덴 가시화 시스템을 소개한다. 개발된 시스템은 분산환경에서 의료영상 분활 및 모델링과 같은 의료영상 분석 및 처리 기능을 제공하며 아울러 의료영상 데이터의 효율적 관리 기능을 제공한다. 영상의 분류 및 특정 세포조직의 추출은 베이지안 방법과 활성 윤곽선 모델등 적용하여 수행되며, 획득된 영상의 특성정보는 의료영상의 실시간 3차원 모델링에 사용된다. 개발된 시스템은 브로드 케스팅과 동기화 메커니즘에 기반하여 시스템을 사용하는 다중 사용자들간의 협동작업을 지원한다. 본 시스템은 분산 프로그램을 지원하는 자바 및 코바에 의해 개발되었으며, 따라서 클라이언트는 분산 객체의 위치나 분산객체가 수행되는 운영체제에 관한 정보가 없이도 메소드 호출방법에 의해 서버 객체에 접근할 수 있다.
