## Abstract

An X-ray emitter includes an emitter housing in which an X-ray tube is disposed and held in the emitter housing by a fixing facility. The fixing facility includes a fixed bearing disposed on the cathode side and a floating bearing disposed on the anode side. At least the floating bearing has at least one damping element. In the X-ray emitter, the X-ray tube is aligned inside the emitter housing and fixed in a respectively low-vibration or vibration-damped manner, resulting in a more stable focus position relative to a beam exit and also a correspondingly improved image quality.

## Claims

### Claim 1

An X-ray emitter, comprising:
an emitter housing;
an X-ray tube disposed in said emitter housing;
a fixing facility holding said X-ray tube in said emitter housing;
said fixing facility including a fixed bearing disposed on a cathode side and a floating bearing disposed on an anode side; and
at least said floating bearing having at least one damping element.

### Claim 2 (depends on 1)

The X-ray emitter according to claim 1, wherein said fixed bearing has at least one damping element.

### Claim 3 (depends on 1)

The X-ray emitter according to claim 1, wherein said X-ray tube is an all-metal tube.

### Claim 4 (depends on 1)

The X-ray emitter according to claim 1, wherein said X-ray tube is a metal center section tube.

### Claim 5 (depends on 1)

The X-ray emitter according to claim 1, wherein said X-ray tube is a metal ceramic tube.

### Claim 6 (depends on 1)

The X-ray emitter according to claim 1, wherein said emitter housing is an X-ray emitter housing.

### Claim 7 (depends on 1)

The X-ray emitter according to claim 1, wherein said emitter housing is a single-tank housing.

### Claim 8 (depends on 1)

The X-ray emitter according to claim 1, wherein said emitter housing is a duo-block.

### Claim 9 (depends on 1)

The X-ray emitter according to claim 1, wherein said fixed bearing includes a tube flange and a fixing flange, said tube flange is fixed rigidly to said X-ray tube and said fixing flange is part of said emitter housing.

### Claim 10 (depends on 9)

The X-ray emitter according to claim 9, wherein said tube flange encloses an outer periphery of a beam exit window disposed in said X-ray tube.
