POWER SUPPLY CIRCUIT DESIGN FOR TRANSMITTING RF SIGNAL TO MULTIPLE COIL ELEMENTS IN MAGNETIC-RESONANCE COIL SYSTEM

摘要

FIELD: radio engineering, communication.;SUBSTANCE: circuit design comprises a main line for connecting the RF signal source; a plurality of the feed lines, each feed line for connecting the respective coil element of the coil system; a power splitter disposed between the main line and the plurality of the power supply lines for distributing the signal on the main line in each feed line, wherein, at least, one of the feed lines comprises a controlled switching circuit with a switching element for connecting/disconnecting two formed linear sections of the feed line, the first linear section being on the separator side and the second linear section - on the side connected to the coil element, and wherein the switching circuit further comprises, at least, one attachable terminal load element for the linear terminal load of the first linear section, or the main line contains a circulatory device connected with the terminal load element. The invention further relates to the corresponding system of parallel transceiving.;EFFECT: enabling the provision of the simple but dynamically switchable power circuit design for supplying the RF signal to the plurality of coils of the magnetic-resonance coil system, and of the parallel transceiving system for the magnetic-resonance system with the magnetic-resonance coil system comprising the plurality of the coil elements.;14 cl, 10 dwg
