摘要：
PURPOSE: An image processing method, an apparatus thereof, and a medical imaging system using the same are provided to reduce a coated amount of a subject by reducing an amount of information required for a tomosynthesis process.CONSTITUTION: A first intermediate reconstructed image generation part(410) generates a first intermediate reconstructed image by applying a first iteration restoration algorithm in an original tomographic image. A second intermediate reconstructed image generation part(430) generates a second intermediate reconstructed image using the original tomographic image and the first intermediate reconstructed image. A re-projection part(431) converts the first intermediate reconstructed image into a sonogram. A differential image generation part(433) generates a differential image by calculating a difference between data extracted from the sonogram and the original tomographic image. An inverse projection part(435) applies an inverse projection technique to a signal to be reconstructed. A reconstructed image generation part(437) generates the second intermediate image which includes an edge element. A synthesizing part(450) generates a final reconstructed image by synthesizing the first intermediate reconstructed image and the second intermediate reconstructed image.COPYRIGHT KIPO 2012영상 처리 방법 및 장치와 이를 채용한 의료영상시스템이 개시되어 있다. 영상 처리 장치에서 제1 중간 복원영상 생성부는 소정 피사체에 대한 단층 영상에 대하여 제1 반복 복원 알고리즘을 적용하여 제1 중간 복원영상을 생성한다. 제2 중간 복원영상 생성부는 제1 중간 복원영상과 단층 영상과의 차영상에 대하여 제2 반복 복원 알고리즘을 적용하여 제2 중간 복원영상을 생성한다. 합성부는 제1 중간 복원영상과 제2 중간 복원영상을 합성하여 최종 복원영상을 생성한다.
