| description | A radio-frequency control system for a magnetic resonance tomography system and a method for the operation thereof are provided. The radio-frequency control system includes a controller and a radio-frequency power amplifier with amplification between a signal input and a signal output of the radio-frequency power amplifier that is dependent on a predetermined frequency response. The controller determines a control pulse for multislice excitation and outputs the pulse to the signal input of the radio-frequency power amplifier. The controller determines a high-frequency power value for the control pulse in dependence on the predetermined frequency response of the radio-frequency power amplifier.
本发明涉及一种用于磁共振断层成像设备的高频控制器和其运行方法。高频控制器具有控制器和高频功率放大器，该高频功率放大器在高频功率放大器的信号输入端和信号输出端之间具有与预先确定的频率响应相关的增益。控制器确定用于多层激励的控制脉冲，并且将其输出到高频功率放大器的信号输入端。控制器依据高频功率放大器的预先确定的频率响应确定用于控制脉冲的高频功率值。 |
