摘要： A switch matrix has a set of inputs, a set of outputs, controllable switch elements and a conductor arrangement that is connected to the inputs and outputs and to the controllable switch elements. The controllable switch elements together with the conductor arrangement produce switched electrical connection paths between at least two inputs and an output. The electrical connection paths contain connecting branches that, proceeding from the at least two inputs and the output, meet at a junction point. The connecting branches connected to the at least two inputs have identical electrical lengths up to the junction point.

摘要： In a method for determining the position of at least one local antenna in an examination chamber of a magnetic resonance apparatus, magnetic resonance signals emitted by a body arranged in the examination chamber are received, locus-encoded in at least one coordinate direction, by an antenna that has a homogeneous sensitivity distribution. From the received magnetic resonance signals, image data that are locus-resolved in the at least one coordinate direction are produced in the form of first intensity values. Magnetic resonance signals emitted by the body are received, locus-encoded in the coordinate direction, by the at least one local antenna. From the received magnetic resonance signals, image data that are locus-resolved in the at least one coordinate direction are produced in the form of second intensity values. From the second intensity values, normalized intensity values are formed by relating the second intensity values respectively to the first intensity values belonging to the same coordinate values. The normalized intensity values are searched for their largest value. A coordinate value that belongs to the largest normalized intensity value indicates the position of the at least one local antenna in the coordinate direction.

摘要： An antenna for a magnetic resonance apparatus has an antenna conductor that can be adapted to examination regions of different sizes, with one region of the antenna conductor divided into conductor sections. The conductor sections are connected to one another via capacitive elements, with the conductor sections and the capacitive elements connected alternating in series. The conductor sections are connectable to the remaining antenna conductor via releasable electrical connections.

摘要： A double surface coil for a nuclear magnetic resonance apparatus has two individual coils which are connectable to a transmission/reception circuit via a matching network. The coils are connected together at a junction. Each coil has a controllable switch connected between the junction and the matching circuit. The individual surface coils can thus be controlled with a low number of controlled elements in any desired operating mode.

摘要： In a local antenna arrangement for a magnetic resonance apparatus, an antenna structure is connected to a signal generator via an inhibiting circuit. The signal generator is fashioned to generate and emit a detection signal from the radio-frequency signal received from the antenna structure when the local antenna is not connected. The inhibiting circuit is fashioned to electrically decouple the signal generator from the antenna structure when the local antenna is connected.
