Abstract: A local coil facility is disclosed for a magnetic resonance tomography apparatus for examining an examination object. In at least one embodiment, the local coil facility includes at least one electronic processing system, a high frequency antenna, and an antenna housing to cover the high-frequency antenna and the at least one electronic processing system, the antenna housing having at least one wall close to the object and at least one wall away from the object. To reduce or even minimize the attenuation of PET radiation in a combined MR/PET device and thus in particular to ensure a better signal to noise ratio for the PET measurement, it is proposed according to at least one embodiment of the invention that the surfaces of the wall away from the object are essentially tangential to the examination object.

Abstract: 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.

Abstract: 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.

Abstract: 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.

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.

Abstract: A local coil unit for acquisition of a magnetic resonance signal of an examination subject, and that can be placed directly on this examination subject, has a deformable section that can be adapted to a contour of the examination subject by a bending mechanism. During acquisition of the magnetic resonance signal, a high signal-to-noise ratio thus can be achieved, which leads to a good image quality. Due to its deformability, the local coil unit is suited for use for sensitive magnetic resonance data acquisition from different examination subjects.
