摘要：
The present invention relates to a variable apparatus for adjusting the irradiation range of a digital tomosynthesis system of a trapezoid shape wherein the side of a direction where an X-ray tube moves is configured to have a trapezoid shape that is longer in length than the side of the opposite direction. The present invention relates to an automatic variable apparatus for adjusting the irradiation range of a chest digital tomosynthesis system and a method for controlling the automatic variable apparatus for adjusting the irradiation range capable of obtaining the necessary information of a patient image without omission and reducing exposure dose of a patient wherein the form of an X-ray to which an apparatus for adjusting an irradiation range of a trapezoid shape is configured to adjust to fit the size of a detector. The present invention relates to a digital tomosynthesis system comprising: an X-ray source for irradiating an X-ray an apparatus for adjusting an irradiation range that adjusts the shape and size of a flux emitted from the X-ray source a detector for detecting an X-ray projection image that is projected through the apparatus for adjusting an irradiation range from the X-ray source and a control apparatus for control the movement of the X-ray source and the detector. In the X-ray irradiation window of the apparatus for adjusting an irradiation range, the side of a direction where an X-ray tube moves is configured to have a trapezoid shape that is longer in length than the side of the opposite direction. The control apparatus is characterized by adjusting the size of an oblique side of the X-ray irradiation window of the apparatus for adjusting the irradiation range so that the form of an X-ray irradiated to a patient fits to the size of a detector.COPYRIGHT KIPO 2016본 발명은, 디지털 단층영상합성 시스템의 가변형 조사범위 조절장치가, X선관이 이동하는 방향의 변이, 반대 방향의 변보다, 길이가 긴 형태의 사다리꼴 형태를 취하도록 이루어진 사다리꼴 모양의 조사범위 조절장치로서, 이 사다리꼴 모양의 조사범위 조절장치가 조사되는 X선의 형태를 검출기의 크기에 맞추어 조절하도록 이루어져, 환자영상에
