More Information
Summary:The present invention provides a medical image apparatus and a control method thereof. The medical image apparatus can increase accuracy of lesion classification by extracting desired feature information from at least one projection image obtained by projecting three-dimensional volume data of an object in at least one direction among an x-axis, a y-axis, and a z-axis. According to one embodiment, the medical image apparatus includes: a scanner which obtains projection data of the object at a plurality of points of view; and a data processing unit which generates volume of interest by using the projection data, generates at least one two-dimensional re-projection image by re-projecting the volume of interest in the one direction, and extracts feature information from the two-dimensional re-projection image. 대상체의 3차원 볼륨 데이터를 x축, y축 및 z축 방향 중 적어도 한 방향에서 투영하여 얻은 적어도 하나의 투영 영상으로부터 원하는 특징 정보를 추출함으로써 병변 분류의 정확도를 높일 수 있는 의료 영상 장치 및 그 제어 방법을 제공한다. 일 실시예에 따른 의료 영상 장치는 복수의 시점(view)에서 대상체의 투영 데이터를 획득하는 스캐너; 및 상기 투영 데이터를 이용하여 관심 볼륨을 생성하고, 상기 관심 볼륨을 적어도 하나의 방향에서 재투영(reprojection)하여 적어도 하나의 2차원 재투영 영상을 생성하고, 상기 적어도 하나의 2차원 재투영 영상으로부터 특징 정보를 추출하는 데이터 처리부; 를 포함한다.
