摘要：
Disclosed are a method and an apparatus for generating an X-ray image, capable of obtaining an X-ray image with a clear boundary of a lesion region and reduced noise. According to one embodiment of the present invention, the method for generating an X-ray image comprises the steps of: obtaining a 2D image by performing a first main shot in which an object is irradiated by an X-ray beam at least once obtaining a plurality of 2D images by performing a second main shot in which the object is irradiated by X-ray beams from different positions and generating a final 2D image by deleting lesion regions with an unclear boundary from the 2D images and replacing the deleted lesion regions with the lesion region of the 2D image.COPYRIGHT KIPO 2014[Reference numerals] (AA) Start (BB) End (S710) Check the thickness of breast (S720) Perform free-shot and obtain free-shot images (S730) Determine the density of breast (S740) Determine shooting conditions considering at least one among the thickness or density of the breast (S750) Obtain two-dimensional images of one by performing a first main shot (S760) Obtain a plurality of two-dimensional images by performing a second main shot (S770) Generate final two-dimensional images by replacing a lesion regions removed in a plurality of two-dimensional images with the lesion region of the two-dimensional image노이즈가 적으면서도 병변 영역의 경계가 선명한 엑스선 영상을 얻을 수 있는 엑스선 영상 생성 방법 및 장치가 개시된다. 엑스선 영상 생성 방법의 일 실시예는 대상체로 엑스선을 적어도 1회 조사하는 1차 메인샷을 수행하여 하나의 2차원 영상을 얻는 단계 서로 다른 위치에서 상기 대상체로 엑스선을 조사하는 2차 메인샷을 수행하여 복수의 2차원 영상을 얻는 단계 및 상기 복수의 2차원 영상에서 주변과의 경계가 불분명한 병변 영역을 삭제하고, 상기 삭제된 병변 영역을 상기 하나의 2차원 영상의 병변 영역으로 대체하여 2차원 최종 영상을 생성하는 단계를 포함할 수 있다.
