摘要： In a magnetic resonance system and an operating method therefor, a number of independently operable radio frequency signal generator modules are provided or respectively connected to radio frequency coils. A control unit provides a synchronization signal to each of the radio frequency signal generator modules to selectively operate the modules to achieve different types of signal transmission. One of the radio frequency signal generator modules can serve as a master module, that receives the synchronization signal directly from the control unit, and supplies the synchronization signal to the other modules, functioning as slave modules.

摘要： A magnetic resonance tomography system has a frequency control device for temperature compensation, a temperature sensor, and a high frequency generator. An output frequency of an output signal from the high frequency generator is dependent on a value of a digital frequency variable, and a synthesis signal with the system frequency is generated dependent on the output signal. A temperature change is detected using the temperature sensor, a temperature-time function of the temperature is determined using the temperature change that has been detected, a time is determined at which a change in the digital frequency variables in the least significant bit brings about a change in the frequency of the synthesis signal that corresponds with a change in the system frequency due to a temperature, according to the interpolated temperature-time function, and the digital frequency variable in the least significant bit is changed at the specified time.
