摘要： A crossbar switch comprises a number of crossing points at which controllable switch elements are arranged, via which an input signal supplied to a row can be interconnected to a column intersecting this row at this crossing point when an interconnection signal is supplied to the respective setting parameter via a control input. The controllable switch elements comprise amplifier elements whose amplifier inputs are connected with the rows and whose amplifier outputs are connected with the columns. The amplifier elements are wired such that they only consume electrical energy when the interconnection signal is supplied to the respective crossing point.

摘要： In a magnetic resonance system and an operating method therefor, a B1 field distribution of a radio-frequency antenna is measured in at least one part of a examination volume of the magnetic resonance system, and then the RF pulses emitted by the radio-frequency antenna are optimized, based on the determined B1 field distribution, for homogenization in a specific volume. An effective volume within the examination volume is determined beforehand for each applied RF pulse and, based on the determined B1 field distribution, the appertaining RF pulse is individually adjusted such that the B1 field is homogenized within the effective volume of the RF pulse.

摘要： A duplexer for an ultrasound imaging system is capable of selectively coupling a transducer element to either a transmitter or a receiver, depending on whether the imaging system is in the transmit mode or receive mode. The duplexer contains a field-effect transistor whose source and drain are connected between the transducer element and the receiver. The gate of the field effect transistor may either be driven with a control voltage or short-circuited to the source. In this manner, one obtains an improved duplexer that operates with virtually no power loss, without drive circuits, without leakage currents, and with low noise.

摘要： In a method and device for the transmission of a multiplicity of signals having different frequencies between a base station and a module situated at a location remote from the base station via a single, common cable connection, some of the signals being transmitted from the electronic assembly to the module and, in general simultaneously, the remaining signals are transmitted in the opposite direction. Each of the base station and the module has bandpass filter bank therein having a multiplicity of bandpass filters, the number thereof being a function of the number of channels to be transmitted, with which the respectively received signals are spectrally separated from one another so that they are available for further signal processing in the base station, or for further use in the module.

摘要： A radio frequency transmitter arrangement for a magnetic resonance apparatus has a distribution unit and an antenna unit, wherein the antenna unit, to generate radio frequency fields, is fashioned in at least two orthogonal modes, and the distribution unit is fashioned for the division of an RF transmission signal into at least two mode feed signals. At least one adjustment unit is provided to adjust the amplitude and/or phase of one of the mode feed signals and is connected with the antenna unit such that each of the mode feed signals generates a radio frequency field in one of the modes. A multiple transmitter arrangement has at least two radio frequency transmitter arrangements and at least two 180° hybrids. A method is provided to determine at least one setting parameter of the adjustment unit.
