摘要： An amplifier device has an input distributor block to which a radio-frequency input signal to be amplified can be fed via an input and that has a number of distributor elements connected in series. The input signal to be amplified is fed to the first distributor element as its input signal. Each distributor element splits the input signal supplied thereto into a divided signal and a remainder signal. With the exception of the first distributor element, each distributor element feeds its divided signal to a corresponding main amplifier of an amplifier block. With the exception of the last distributor element, each distributor element feeds its remainder signal to another distributor element as its input signal. Each main amplifier amplifies the divided signal fed to it into a corresponding amplified partial signal and feeds the amplified partial signal to a corresponding main combiner element of an output combiner block. Each main combiner element combines the amplified partial signal supplied to it with a further signal to form a sum signal. The main combiner elements are connected in series with one another so that, with the exception of the first main combiner element, the sum signal of another main combiner element is supplied to each main combiner element as a further signal. The sum signal emitted by the last main combiner element is supplied to an output. The distributor elements, the main amplifiers and the main combiner elements are designed such that the divided signals exhibit identical amplitudes among one another, the amplified partial signals exhibit identical amplitudes among one another and the delay from input to output is the same for all main amplifiers.

摘要： An amplifier device has an amplifier circuit, an energy supply device, a switching matrix and a control device. A radio-frequency, low-energy signal pulse can be amplified into a high-energy power pulse by the amplifier circuit. The amplifier circuit is supplied with electrical energy by the energy supply device. The energy supply device has a number of electrical energy sources that are separated in terms of potential relative to one another in a state in which they are not connected to the amplifier circuit. The electrical energy sources can be selectively connected to the amplifier circuit by the switching matrix. The switching state of the switching matrix can be dynamically set for this purpose by the control device.

摘要： An arrangement to control an antenna arrangement in a magnetic resonance examination representatively has a device for signal splitting. This device has an input and a first input and a second output. A radio-frequency transmission signal is supplied at the input. The device for signal splitting has phase-shaping components with which the transmission signal supplied via the input is divided into a first transmission signal for the first output and a second transmission signal for the second output. A phase difference between the first transmission signal and the second transmission signal can be adjusted by the phase-shaping components. An antenna arrangement is provided that has a first and second connections and that is fashioned to radiate a circularly-polarized transmission signal as soon as the two transmission signals with a phase difference of 90° are present at both connections. Each output of the device for signal splitting is connected with an associated connection of the antenna arrangement. The device for signal splitting has switchable components with which selected ones of the phase-shaping components can be activated or deactivated in order to alter the phase difference.

Each distributor element splits the input signal supplied thereto into a divided signal and a remainder signal. The divided signal and the remainder signal are appropriately amplified and re-combined by combiner elements.

The geometry of the transmission coil is permanently prescribed. For acquiring the magnetic resonance signal, the reception arrangement includes at least one first local coil. This is secured to a movable carrier, so that it can be placed against the person from a remote position. The carrier is secured in a carrier mount arranged stationarily within the examination volume.

摘要： In a magnetic resonance transmission method and magnetic resonance transmission operating therewith a high-frequency power amplifier emits an output signal with an actual amplitude and an actual phase to a magnetic resonance transmission antenna. A fraction of the signal is digitilized in a magnetic resonance receiver and is supplied to a pulse controller that is realized in software. An analog magnetic resonance reception signal of an object can be supplied to the magnetic resonance receiver during the pulses. The pulse controller determines correction values for a generator amplitude and a generator phase with which a pulse generator is driven, the pulse generator being connected upstream relative to the high-frequency amplifier.
