The x-ray device includes an x-ray emitter, an image receiver arranged in a radiation direction at a distance from the x-ray emitter, a patient support disposed between the x-ray emitter and the image receiver, a relative position of the x-ray emitter and the image receiver being adjustable with respect to the patient support in at least one spatial direction, and a scattered ray protection device, which can be fixed in a fixed relative position with respect to the image receiver and/or the x-ray emitter as a reference object using a coupling unit the scattered ray protection device being entrained with the reference object when the reference object is adjusted with respect to the patient support. ## Claims ### Claim 1 An x-ray device comprising: an x-ray emitter, an image receiver arranged in a radiation direction at a distance from the x-ray emitter, a patient support disposed between the x-ray emitter and the image receiver, where the image receiver is adjustable with respect to the patient support in at least one spatial direction without adjusting the x-ray emitter, and a scattered ray protection device that is fixed to the image receiver using a plug-in connector, the scattered ray protection device being a self-supporting screen that is fixed to the image receiver such that when the image receiver is adjusted with respect to the patient support, the scatter ray protection device is adjusted with respect to the patient support, wherein the scattered ray protection device comprises a substantially flat body panel with a plane that is aligned approximately parallel to a front edge of the patient support and approximately vertical to a patient support surface of the patient support, an upper edge of the body panel facing away from the patient support comprises a viewing panel angled away from the upper edge in a direction towards the patient support, wherein a moveable sliding panel is disposed on at least one edge of the body panel, the sliding panel enlarging a surface region of the body panel in a normal position and being moveable from the normal position into a release position, the release position being retracted at least partially into the surface region of the body panel, the sliding panel being movable from the normal position against a restoring force, wherein the sliding panel is suspended in a pivotable manner such that a force of gravity that impacts the sliding panel is a restoring force, and wherein the sliding panel is pretensioned by a spring element that generates the restoring force in the normal position. ### Claim 2 (depends on 1) The x-ray device as claimed in claim 1, wherein at least one side edge of the body panel comprises a recess. ### Claim 3 (depends on 1) The x-ray device as claimed in claim 1, wherein a fixing element is operable to fix the sliding panel in the normal position. ### Claim 4 (depends on 1) The x-ray device as claimed in claim 1, wherein the scattered ray protection device can be removed from the normal position predetermined by the plug-in connector with respect to the patient support. ### Claim 5 (depends on 1) The x-ray device as claimed in claim 1, wherein the scattered ray protection device comprises a transparent, x-ray beam-absorbent material. ### Claim 6 (depends on 5) The x-ray device as claimed in claim 5, wherein the x-ray beam-absorbent material is lead acrylic glass. ### Claim 7 (depends on 1) The x-ray device as claimed in claim 1, wherein the scattered ray protection device includes a number of operating and control elements. ### Claim 8 An x-ray device comprising: an x-ray emitter, an image receiver arranged in a radiation direction at a distance from the x-ray emitter, a patient support disposed between the x-ray emitter and the image receiver, where the image receiver is adjustable with respect to the patient support in at least one spatial direction without adjusting the x-ray emitter, and a scattered ray protection device that is fixed to the image receiver using a plug-in connector, the scattered ray protection device being a self-supporting screen that is fixed to the image receiver such that when the image receiver is adjusted with respect to the patient support, the scatter ray protection device is adjusted with respect to the patient support, wherein the scattered ray protection device comprises a substantially flat body panel with a plane that is aligned approximately parallel to a front edge of the patient support and approximately vertical to a patient support surface of the patient support, a moveable sliding panel being disposed on at least one edge of the body panel, the sliding panel enlarging a surface region of the body panel in a normal position and being moveable from the normal position into a release position, the release position being retracted at least partially into the surface region of the body panel, the sliding panel being movable from the normal position against a restoring force and being pretensioned by a spring element that generates the restoring force in the normal position. ### Claim 9 (depends on 8) The x-ray device as claimed in claim 8, wherein at least one side edge of the body panel comprises a recess. ### Claim 10 (depends on 8) The x-ray device as claimed in claim 8, wherein a fixing element is operable to fix the sliding panel in the normal position. ### Claim 11 (depends on 8) The x-ray device as claimed in claim 8, wherein the scattered ray protection device can be removed from the normal position predetermined by the plug-in connector with respect to the patient support. ### Claim 12 (depends on 8) The x-ray device as claimed in claim 8, wherein the scattered ray protection device comprises a transparent, x-ray beam-absorbent material. ### Claim 13 (depends on 12) The x-ray device as claimed in claim 12, wherein the x-ray beam-absorbent material is lead acrylic glass. ### Claim 14 (depends on 8) The x-ray device as claimed in claim 8, wherein the scattered ray protection device includes a number of operating and control elements.
