摘要： 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.

摘要： A magnetic resonance system that has a magnet system that generates magnetic fields in an excitation region, allowing nuclei in an examination subject in the excitation region to be excited to emit a magnetic resonance signal. A reception antenna device with multiple local coils for reception of the magnetic resonance signals is arranged in proximity to the examination subject, and has a base part and an attachment part. The attachment part can be placed on the base part such that the examination subject is located between the base part and the attachment part (6). The multiple local coils are respectively connected with an evaluation device for evaluation of magnetic resonance signals. To simply and reliably couple the antenna devices to an evaluation device with optimally few electrical conductors being located in the excitation region, the multiple local coils in the attachment part are respectively connected with the evaluation device via a base coupling element that is arranged at a predetermined base part location on the base part and an attachment coupling element is arranged at a predetermined attachment part location on the attachment part. The magnetic resonance signal received by the local coil can be fed to the evaluation device via the attachment coupling element and the base coupling element and as long as the attachment part is placed on the base part.

摘要： A simple connection of a coil with a magnetic resonance tomography (MRT) is facilitated by a method and an adapter wherein a coil-connection element of at least one local coil is connected with an MRT-connection element of an MRT system. The adapter has a coil-connection element adapter designed to form a connection with at least one coil-connection element of at least one local coil. The adapter also has at least one MRT-connection element adapter designed to form a connection with an MRT-connection element of an MRT system. The adapter can be fixed mechanically to a fixing element of the MRT system.
