    摘要： In a contacting system and method for contacting magnetic resonance local coils with a unit for additional signal processing of a magnetic resonance data acquisition unit, a number of coil coupler elements are electrically connected with the magnetic resonance local coils and apparatus coupler elements are mounted at the magnetic resonance tomograph, and are electrically connected with a unit for signal processing. The coil coupler elements and the apparatus coupler elements are fashioned so that, given a movement of the local coils along a movement path in the magnetic resonance data acquisition unit, a successive contacting of at least a portion of the coil coupler elements with apparatus coupler elements ensues at least over a specific path segment of the movement.

    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： An arrangement and a support device for attaching local coils to a patient for a magnetic resonance examination includes at least one local coil that is designed to acquire magnetic resonance signals and a support device. The support device is designed to accommodate the at least one local coil and to attach the at least one local coil on the patient. The support device is designed as a gas-filled cushion that changes its shape dependent on the gas pressure therein. The gas-filled cushion has a device for changing the gas pressure, such when a gas pressure change occurs the local antenna is pressed on the patient due to the resulting change in shape of the cushion.
