Abstract
A movement system for a C-arm. The movement system comprises at least one first guide element arranged in a plane, a movement device arranged to allow movement along the first guide element as well as a first motion link rotatable around a first axis of rotation standing at right angles to the plane. The movement device is connected rotatably to the first motion link to a second axis of rotation standing at right angles to the plane such that a movement of the movement device along the first guide element causes the second axis of rotation to be moved on a circular track around the first axis of rotation. The advantage of this is that the arm is prevented from jamming as a result of leverages during movement of a C-arm.

A movement system for a c-arm arranged on a trolley, the movement system comprising:
- at least one first guide element arranged in a plane,
- a movement device arranged movably along the at least one first guide element, a first motion link that is rotatable around a first axis of rotation at right angles to the plane, the movement device and the first motion link being connected to a second axis of rotation standing at right angles to the plane such that a movement of the movement device along the at least one first guide element causes the second axis of rotation to move on a circular track around the first axis of rotation,
- a second motion link forming the rotatable connection between the movement device and the first motion link, and
- at least one second guide element arranged on the second motion link in parallel to the plane and at right angles to the at least one first guide element, the movement device being moveable along the at least one second guide element.
A C-arm comprising:
- an x-ray emitter operable to emit x-radiation,
- an x-ray detector operable to detect the x-rays emitted from the x-ray emitter, and
- a movement system comprising:
- at least one first guide element arranged in a plane,
- a movement device arranged movably along the at least one first guide element,
- a first motion link that is rotatable around a first axis of rotation at right angles to the plane, the movement device and the first motion link being connected to a second axis of rotation standing at right angles to the plane such that a movement of the movement device along the at least one first guide element causes the second axis of rotation to move on a circular track around the first axis of rotation,
- a second motion link forming the rotatable connection between the movement device and the first motion link, and
- at least one second guide element arranged on the second motion link in parallel to the plane and at right angles to the at least one first guide element, the movement device being moveable along the at least one second guide element,
- wherein the C-arm is arranged on the movement device such that the C-arm is moveable in parallel to a patient bed.
An x-ray movement device comprising:
- a C-arm comprising:
- an x-ray emitter operable to emit x-radiation,
- an x-ray detector o erable to detect the x-rays emitted from the x-ray emitter, and
- a movement system comprising:
- at least one first guide element arranged in a plane,
- a movement device arranged movably along the at least one first guide element,
- a first motion link that is rotatable around a first axis of rotation at right angles to the plane, the movement device and the first motion link being connected to a second axis of rotation standing at right angles to the plane such that a movement of the movement device along the at least one first guide element causes the second axis of rotation to move on a circular track around the first axis of rotation,
- a second motion link forming the rotatable connection between the movement device and the first motion link, and
- at least one second guide element arranged on the second motion link in parallel to the plane and at right angles to the at least one first guide element, the movement device being moveable along the at least one second guide element,
- wherein the C-arm is arranged on the movement device such that the C-arm is moveable in parallel to a patient bed.
