Claims

[Scope of utility model registration request]

In an X-ray tube equipped with a rotating anode target and a focusing electrode disposed facing the anode target at a position offset from the central axis of rotation of the anode target, the anode target is attached to an end of the focusing electrode. An inclined surface formed by changing the inclination angle in the middle symmetrically with respect to a plane perpendicular to the normal line from the rotation center axis, and each of these inclined surfaces is symmetrical with respect to the axis of symmetry of the valley bottom of the inclined surface. filament mounting grooves that are drilled in the same direction, and filaments that are installed in the filament mounting grooves and are arranged symmetrically among the plurality of filament mounting grooves, and that have different shapes and dimensions for each pair, and that are lighted separately for each pair. An X-ray tube comprising:
