Abstract

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.
