X-ray recording system

1. An x-ray recording system, comprising:

an x-ray emitter for generating a beam used for imaging;

an imaging x-ray detector with a two-dimensional or three-dimensional recording geometry for determining an attenuation of rays of the beam;

a patient bearing and/or positioning device for a patient, in a recording region of the x-ray recording system between said x-ray emitter and said x-ray detector;

at least one time-of-flight (TOF) camera for establishing a contour of the patient;

a computer unit with a memory and software stored in said memory, said computer unit embodied, during operation, to generate a three-dimensional wire model of the patient with joint locations disposed therein from the contour of the patient recorded by said TOF camera and to simulate and display at least one virtual anatomical structure generated by statistical examination of the patient and scaled to the three-dimensional wire model; and

a projection system for projecting the at least one virtual anatomical structure onto the patient situated on said patient bearing and/or positioning device.

2. The x-ray recording system according to claim 1 , wherein the at least one anatomical structure is a structure selected from the group consisting of a skeleton, a venous and/or arterial structure, and an organ structure.

3. The x-ray recording system according to claim 1 , wherein said software stored in said computer unit is embodied to set a patient positioning in an automated manner in accordance with the at least one anatomical structure on a basis of a predetermined recording region by setting said patient bearing and/or positioning device and/or setting location and position of said x-ray emitter and/or said x-ray detector relative to one another and to the patient.

4. The x-ray recording system according to claim 1 , further comprising:

a monitor; and

an optical camera for depicting the patient on said monitor, wherein the software stored in said computer unit is embodied to superpose, on said monitor, the at least one anatomical structure with a representation of the patient.

5. The x-ray recording system according to claim 1 , wherein the software stored in said computer unit is embodied to display the recording region to be irradiated by the beam.

6. The x-ray recording system according to claim 1 , wherein the software stored in said computer unit is embodied to automatically align a spatial position of said x-ray emitter in accordance with regions of the at least one anatomical structure to be recorded.

7. The x-ray recording system according to claim 6 , further comprising a table or database specifying an ideal alignment of said x-ray emitter relative to a region of the anatomical structure.

8. The x-ray recording system according to claim 1 , wherein said TOF camera is part of a KINECT or XTION acquisition system.

9. The x-ray recording system according to claim 1 , wherein said TOF camera is disposed next to said x-ray emitter or next to said x-ray detector.

10. The x-ray recording system according to claim 1 , wherein the x-ray recording system is configured as a C-arm system.

11. The x-ray recording system according to claim 1 , wherein the x-ray recording system is embodied as a projective radiography system.

12. The x-ray recording system according to claim 11 , further comprising articulated arms, said x-ray emitter and said x-ray detector are disposed on said articulated arms in a manner independent of one another and freely movable in space.
