摘要：
A lung image registration method for histogram analysis of lung motion is provided. The lung image matching method for histogram analysis of the lung motion is a lung image acquisition step in which a computer acquires two lung images by tomography, and the computer divides the lung region from one lung image of the two lung images Generating a floating image by generating a floating image, wherein the computer generates a reference image by dividing a lung region from one of the two closed images and the other lung image from the floating image. A first matching step of matching the floating image and the reference image as a whole, and a second matching of the floating image to the reference image by matching the internal structures of blood vessels and bronchi of the floating image and the reference image When the intake lung image and the exhalation lung image are matched, the floating image is the inhalation lung image, the reference image is the exhalation lung image, and when the intake lung image of different viewpoints is matched, the floating The image is an intake lung image at a reference time point, and the reference image is an intake lung image at a next time point of the floating image, and when matching an aerobic lung image at another time point, the floating image is an aerobic lung image at a reference time point and the reference The image is an aerobic lung image at the next time point of the floating image, and the second matching step matches the internal structure of the blood vessels and the bronchus based on the mark indicating the bifurcation of the bronchus and the mark indicating the bifurcation of the peripheral pulmonary vessels. It is characterized by letting.폐 운동의 히스토그램 분석을 위한 폐 영상 정합 방법이 제공된다. 상기 폐 운동의 히스토그램 분석을 위한 폐 영상 정합 방법은 컴퓨터가 단층 촬영에 의해 2개의 폐 영상을 획득하는, 폐 영상 획득 단계, 상기 컴퓨터가 상기 2개의 폐 영상 중 하나의 폐 영상으로부터 폐 영역을 분할하여 부유 영상을 생성하는, 부유 영상 생성 단계, 상기 컴퓨터가 상기 2개의 폐 영상 중 상기 부유 영상과 다른 하나의 폐 영상으로부터 폐 영역을 분할하여 기준 영상을 생성하는, 기준 영상 생성 단계, 상기 컴퓨터가
