Section: claims

1. An X-ray apparatus comprisingan X-ray source configured for producing an X-ray beam and comprising a focus position;a detector configured for detecting X-radiation;a collimator arrangement comprising at least one collimator structure, positioned between the focus position and the detector;mechanics that move the collimator arrangement, the detector and the X-ray source along a curved scan trajectory travelling through an x-z plane and extending along a y-axis perpendicular to the x-z plane; anda control unit configured for controlling the mechanics to move the collimator arrangement, the detector and the X-ray source along the curved scan trajectory, wherein a curvature of the curved scan trajectory is adjustable. 2. The X-ray apparatus as claimed in claim 1, wherein the mechanics comprise:a base element;a moving element, to which the detector and/or the collimator arrangement and/or the X-ray source is connected and which is configured to move relative to the base element; anda guiding element configured for guiding the moving element along the curved scan trajectory. 3. The X-ray apparatus as claimed in claim 2, wherein the guiding element is rotatably connected to the base element and the moving element is rotatably connected to the guiding element. 4. The X-ray apparatus as claimed in claim 2, wherein the guiding element is curved. 5. The X-ray apparatus as claimed in claim 1, wherein the curvature of the curved scan trajectory is adjustable by adjustment of an effective length of the guiding and/or moving element. 6. The X-ray apparatus of claim 2, wherein the guiding element is configured as a parallelogram. 7. The X-ray apparatus of claim 5, further comprising a stepper motor that adjustably controls the effective length. 8. The X-ray apparatus of claim 1, further comprising an arm that connects the X-ray source, the detector, and the collimator arrangement to the mechanics. 9. The X-ray apparatus of claim 1, wherein the collimator arrangement, the detector, and the X-ray source cooperate to acquire X-radiation information at multiple locations along the curved scan trajectory from which imagery of a patient is created. 10. An X-ray apparatus comprisingan X-ray source configured for producing an X-ray beam and comprising a focus position;a detector configured for detecting X-radiation;a collimator arrangement comprising at least one collimator structure, positioned between the focus position and the detector;mechanics comprising: a base element; a moving element, to which the detector and/or the collimator arrangement and/or the X-ray source is connected and which is configured to move relative to the base element; and a guiding element configured for guiding the moving element along a, curved scan trajectory, the mechanics adapted to move the collimator arrangement, the detector and the X-ray source along the curved scan trajectory travelling through an x-z plane and extending along a y-axis perpendicular to the x-z plane, wherein a curvature of the curved scan trajectory is adjustable; anda control unit configured for controlling the mechanics to move the collimator arrangement, the detector and the X-ray source along the curved scan trajectory, wherein the guiding element is configured as a parallelogram. 11. The X-ray apparatus of claim 10, further comprising an arm that connects the X-ray source, the detector, and the collimator arrangement to the mechanics. 12. The X-ray apparatus of claim 11, wherein the collimator arrangement, the detector, and the X-ray source cooperate to acquire X-radiation information at multiple locations along the curved scan trajectory from which imagery of a patient is created.
