The present invention relates to an x-ray viewing device for a real-time stereoscopic vision comprising: an x-ray generating unit； and a mode selecting unit. The x-ray generating unit includes: a first x-ray irradiating device and a second x-ray irradiating device which irradiate x-rays to a subject； and detects first x-rays and second x-rays penetrated to the subject by using a predetermined detecting device when the first x-rays and the second x-rays, which are individually irradiated by the first x-ray irradiating device and the second x-ray irradiating device, are penetrated to the subject. The mode selecting unit selects one of a 2D image photographing mode and a 3D image photographing mode. Disclosed is a real-time x-ray viewing device capable of determining an angle for the subject of the first x-ray irradiating device and the second x-ray irradiating device based on one of the 2D image photographing mode and the 3D image photographing mode selected by the mode selecting unit； and providing information for the detected first x-rays and the detected second x-rays to a predetermined image processing unit in order to perform image processing for the first x-rays and the second x-rays detected by the detecting device. The present invention is provided to visualize blood vessels three-dimensionally like real； and to accurately express positions of overlapped blood vessels and a driving path, thereby easily determining a position for a lesion and an approach direction at a procedure time. The present invention easily selects a photographing mode depending on a use purpose by selecting one of the 2D image photographing mode and the 3D image photographing mode.본 발명은, X선을 피사체에 조사하는 제1 X선 조사장치 및 제2 X선 조사장치를 포함하며, 상기 제1 X선 조사장치 및 상기 제2 X선 조사장치 각각에 의해 조사된 제1 X선 및 제2 X선이 상기 피사체에 투과되면, 상기 피사체에 투과된 제1 X선 및 제2 X선이 소정의 검출기에 의해 검출되도록 지원하는 X선 발생부； 및 2D 영상 촬영 모드 및 3D 영상 촬영 모드 중 어느 하나를 선택할 수 있는 모드 선택부를 포함하되, 상기 제1 X선 조사장치 및 상기 제2 X선 조사장치의 상기 피사체에 대한 각도는 상기 모드 선택부에 의해 선택된 상기 2D 영상
