ABSTRACT:
A magnetic resonance system has a base unit and a patient bed. The base unit embodies a magnet system by which magnetic fields can be generated in an excitation region, these magnetic fields causing nuclear spins in an examination subject in the excitation region to be excited to emit a magnetic resonance signal. The patient bed can be moved in a travel direction relative to the base body over a travel range. By movement of the patient bed the examination subject can be brought into the excitation region. A number of base unit coupling elements that are connected with an evaluation device for evaluation of magnetic resonance signals are arranged to be stationary at the base unit relative to the base unit. A number of patient bed coupling elements that are connected with a local coil for acquisition of the magnetic resonance signal are arranged on the patient bed so as to be stationary relative to the patient bed. The base unit coupling elements and the patient bed coupling elements are arranged and fashioned such that the magnetic resonance signal acquired by the local coil can be fed via the patient bed coupling elements and the base unit coupling elements to the evaluation device when and as long as the patient bed has moved by a predetermined segment of the travel range. A degree of coupling with which the patient bed coupling elements and the base unit coupling elements and coupled with one another in total is constant within the segment of the travel range.
