摘要： A method for controlling a signal with a plurality of independent components is provided. The signal is fed as an input signal via an input path to a control path that supplies an output signal. The output signal is fed via an output path to a control apparatus controlling the input signal. A coupling signal is determined in a coupling determination apparatus. On the basis of the coupling signal, the independent components are decoupled in a decoupling apparatus, as a result of which, a decoupled output signal is generated. Components of the decoupled output signal are decoupled from the components of the input signal. The decoupled output signal is fed as a control variable to the control apparatus. The control apparatus controls each independent component separately on the basis of a desired signal with a diagonal controller and outputs the input signal as a manipulated variable.

摘要： In a method and a device for optimization of a combined system for the acquisition of magnetic resonance tomographic measurement data and an image reconstruction process, the image reconstruction process is already executed during the acquisition of the measurement data, by the calculation process being deconstructed into calculation packets, and rules are defined that establish which requirements must be met for the execution of the respective calculation packet. The calculation process is reorganized into a workflow structure based on the calculation packets and the rules. The calculation process is controlled using the generated workflow structure synchronized to the acquisition process. The rules entirely describe the calculation process, i.e. inclusive of all calculation packets and their logical dependencies. The stability of the calculation process is thus entirely independent of the chronological order of the measurement data acquisition.

摘要： A control device for a magnetic resonance system activates the coils of a transmission array and a gradient magnet system of the magnetic resonance system by causing an excitation pulse to be supplied to each coil. A magnetization that exhibits a first actual inhomogeneity thereby is generated in an excitation volume of the magnetic resonance system. The control device determines the excitation pulse for each coil using a start pulse and a maximum allowable inhomogeneity. The respective start pulse has a total time duration. When the control device activates the coils of the transmission array and of the gradient magnet system corresponding to the start pulse, a magnetization that exhibits a second actual inhomogeneity that is smaller than the maximum permissible inhomogeneity is generated in the excitation volume. The control device determines an intermediate point of the start pulse so that the respective start pulse is divided into a first pulse part and a second pulse part that is complementary to the first pulse part. The first pulse part corresponds to a respective low-energy portion of the start pulse, the second pulse part with a high-energy portion of the respective start pulse. The control device temporally extends the second pulse part and correspondingly compresses the second pulse part in terms of amplitude. The temporally extended and amplitude-compressed pulse part is used as the excitation pulse. The control device determines the intermediate point such that the first inhomogeneity is still smaller than the maximum allowable inhomogeneity.

摘要： An amplifier circuit has a transistor element that has an input terminal, an output terminal) and a third terminal. An input signal to be amplified is supplied to the input terminal. The amplified input signal is emitted as an output signal at the output terminal. The input terminal is connected with the output terminal via a first reactance. The third terminal is connected via a second reactance with a zero potential. One of the reactances is fashioned as an inductor and the other of the reactances is fashioned as a capacitor. An inductance value of the inductor and a capacitance value of the capacitor are dimensioned such that the quotient of the inductance value of the inductor and the capacitance value of the capacitor is equal to the product of a desired input impedance that is effective at the input terminal and an output impedance associated with the output impedance. Based on this dimensioning, the output impedance associated with the output terminal is mapped to the input terminal at the same level or scaled.

摘要： A method is disclosed for determining positron emission measurement information in the context of positron emission tomography. The method includes carrying out a positron emission measurement, in a body area of a subject to be examined, to record positron emission measurement information with point resolution and determining a time frame of the measurement by, at the same time, generating images of the body area to be examined with a relatively higher time resolution and with point-resolved image data, using a second imaging method. Further, a local shift of points of individual images of the second imaging method is determined, caused by movement processes of the subject to be examined, and as a function thereof, of the positron emission measurement information for at least a part of the measurement period and of the body area to be examined. Finally, the positron emission measurement information is adjusted as a function of the determined shift.
