    • Provided is one example of a medical X-ray apparatus used as a C-arm fluoroscopy apparatus for endoscopy. Firstly, a three-dimensional image (CBCT volume data) is obtained through cone beam CT imaging (CBCT imaging). Then a stereogram (right and left fluoroscopy images) is generated through endoscopy (fluoroscopy). Thereafter, a stereoscopic image (right and left CBCT images) is generated based on the three-dimensional image (CBCT volume data) in projection directions in the stereogram. The three-dimensional image (stereoscopic image) and the stereogram are same in terms of an X-ray image. Accordingly, these images are superimposed to be displayed in real time on a display unit. This allows identification of a position and a direction of an object under fluoroscopy. Moreover, a three-dimensional coordinate of the object is detected from the stereogram in real time. Consequently, the position and the direction under fluoroscopy can be identified much readily, leading to perform accurate navigation.
    • 提供了用作内窥镜检查用的C型臂透视装置的医疗X射线装置的一例。 首先,通过锥束CT成像(CBCT成像)获得三维图像(CBCT体积数据)。 然后通过内窥镜检查(荧光透视)产生立体图(左右透视图像)。 此后,基于立体图中的投影方向上的三维图像(CBCT体积数据)生成立体图像(右和左CBCT图像)。 关于X射线图像,三维图像(立体图像)和立体图是相同的。 因此,这些图像被叠加以在显示单元上实时显示。 这允许在荧光透视下识别物体的位置和方向。 此外,从立体图实时检测物体的三维坐标。 因此,可以很容易地识别荧光透视下的位置和方向,导致执行准确的导航。
