초록

건강에 대한 관심의 증대로 의료영상이 빠르게 증가하고 있으며, 컴퓨터 기술의 발전으로 의료영상의 디지털화가 빠르게 진전되어 PACS가 의료현장에 도입되었다. 이러한 현상에 의한 의료영상 생산의 증가는 의료영상을 판독하여야 하는 영상의학과 전문의의 업무량을 증가하게 하였다. 이러한 추세에 따라 컴퓨터를 이용한 보조 진단의 필요성이 대두되어 의료영상 판독 분야에 CAD라는 용어가 생겨나게 되었다. 본 연구에서는 디지털 X-선 유방촬영장치에 의하여 획득된 영상의 판독을 위한 CAD 알고리즘을 제안하였다. 제안된 알고리즘을 Visual C++로 프로그램하여 실험하였다. 본 연구에 사용한 일곱 샘플영상을 CAD 알고리즘으로 실행한 결과 다섯 샘플의 결과는 양성종양 및 유방암으로 확인되었고 두 샘플 영상은 error처리 되었다. 본 연구에서 제시한 알고리즘과 이를 구현한 프로그램을 이용한다면 판독업무에 많은 도움이 될 것이며, 유방암의 조기발견에 크게 기여할 것으로 사료된다.

Medical imaging has increased rapidly in the increase of interest in health, with the development of computer technology, digitization of medical imaging is rapidly advancing, PACS has been introduced to the medical field. Increase in the production of medical images by these phenomena made increased the workload of radiologist who must read a medical image. in response to the need for secondary diagnosis using a computer, The term of CAD in medical radiology field was introduced. In this study, we have proposed a CAD algorithm for the interpretation of the image obtained by the digital X-ray mammography equipment. The experiments were performed by programmed in Visual C++ for the proposed algorithm. A result of the execution of the CAD algorithm seven sample images, the results of five samples was confirmed in breast cancer and benign tumors, both the images sample was error processing. If you use a program that implements this with the algorithm proposed in this study it is helpful to reading breast images, and it is considered to contribute significantly to the early detection of breast cancer.
