西门子Impact 1.0T磁共振180°功率分配器原理简介和维修

Brief introduction of principle of 180°power splitter in Siemens Impact 1.0T MR and its maintenance

180°功率分配器除对射频发射信号进行分相外,还负责体线圈的动、静态失调谐。通过两例相关故障的维修,提高对180°功率分配器原理的认识。

180°Power Splitter is responsible for the dynamic and static detune o body coil beside RF signal phase shifting. The ability of understanding the principle of 180°Power Splitter is enhanced by two cases of relevant troubleshooting.
