Abstract
An X-ray device includes a degree-of-wear detection unit for detecting a degree-of-wear of an emitter, an adhesion amount estimation unit for estimating an adhesion amount of a conductive material onto an envelope based on the degree-of-wear of the emitter and a relation between the degree-of-wear of the emitter and an adhesive amount of the conductive material onto the envelope stored in a storage unit.
Claims7
An X-ray device comprising:
- an X-ray generation unit including an emitter made of a conductive material, the emitter being configured to emit electrons, a target for generating X-rays by being collided by the electrons emitted from the emitter, and an envelope accommodating the emitter and the target;
- a degree-of-wear detection unit configured to detect a degree-of-wear of the emitter;
- a storage unit configured to store a relation between the degree-of-wear of the emitter and an adhesion amount of the conductive material constituting the emitter onto the envelope;
- and
- an adhesion amount estimation unit configured to estimate the adhesion amount of the conductive material constituting the emitter onto the envelope based on the degree-of-wear of the emitter and a relation between the degree-of-wear of the emitter and the adhesion amount of the conductive material constituting the emitter stored in the storage unit.
