Claims

[Scope of utility model registration request]

An X-ray camera for stereoscopic imaging, which is equipped with one anode and two cathode parts separated by a finite distance from each other in the same vacuum envelope, and forms two elongated X-ray focal points at corresponding positions of the anode. An X-ray tube device for stereoscopic imaging, characterized in that each X-ray focal point is formed to be inclined inward so that the center of the irradiation field is located on the longitudinal extension of the two elongated X-ray focal points. tube device.
