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.
