Configuration and method for tomosynthetic fluoroscopy
A configuration and an associated operating method for tomosynthetic fluoroscopy utilize an x-ray emitter and with an x-ray detector. The configuration further contains a mounting device, which is rotatably mounted about a rotational axis and about which the x-ray emitter is arranged such that the optical axis of the x-ray emitter is directed to the x-ray detector and that, in the case of a rotation of the mounting device, the focus of the x-ray emitter describes a circular path. An advantage offered by the invention lies in ensuring robust tomosynthetic fluoroscopy.
1. A configuration for tomosynthetic fluoroscopy, comprising:
an x-ray emitter defining an optical axis and a focus;
an x-ray detector;
a mounting device rotatably mounted about a rotational axis and about which said x-ray emitter is disposed such that said optical axis of said x-ray emitter is directed to said x-ray detector and that, in a case of a rotation of said mounting device, said focus of said x-ray emitter describes a circular path; and
said x-ray emitter being displaceably disposed in a direction of the rotational axis.
2. The configuration according to claim 1 , further comprising a counterbalance, which is disposed symmetrically with respect to the rotational axis, opposite to said x-ray emitter on said mounting device.
3. The configuration according to claim 2 , wherein said counterbalance has a same mass as said x-ray emitter.
4. The configuration according to claim 2 , wherein said counterbalance is displaceably disposed in the direction of the rotational axis.
5. The configuration according to claim 1 , wherein said mounting device has a shape of a disk.
6. The configuration according to claim 1 , further comprising an x-ray collimator disposed in front of said x-ray emitter in a direction of the optical axis such that said x-ray collimator rotates together with said x-ray emitter.
7. The configuration according to claim 1 , wherein said mounting device is at least one of displaceable or tiltable.
8. A method for operating a configuration for tomosynthetic fluoroscopy, which comprises the step of:
rotating a mounting device rotatably mounted about a rotational axis, a focus of an x-ray emitter connected to the mounting device carrying out a circular path; and
displacing the x-ray emitter in a direction of the rotational axis.
9. A fluoroscopy instrument, comprising:
an x-ray emitter defining an optical axis and a focus;
an x-ray detector;
a mounting device rotatably mounted about a rotational axis and about which said x-ray emitter is disposed such that said optical axis of said x-ray emitter is directed to said x-ray detector and that, in a case of a rotation of said mounting device, said focus of said x-ray emitter describes a circular path; and
said x-ray emitter being displaceably disposed in a direction of the rotational axis.
