Abstract:
A multi-channel RF transmit system (1) especially for use in a magnetic resonance examination system comprising, a plurality of RF channels (18, 19) wherein each of the RF channels (18, 19) has an RF amplifier. The multi-channel RF transmit system (1) further comprises a power supply device (2) configured to supply power to the amplifiers (4, 5), a first capacitor bank (6), wherein the first capacitor bank (6) is connected to the power supply device (2) and connected to a first RF amplifier (4), a second capacitor bank (7), wherein the second capacitor bank (7) is connected to the power supply device (2) and connected to a second RF amplifier (5) and a third capacitor bank (8) also connected to the power supply device (2). The third capacitor bank (8) is connected to a DC switch (9), wherein the DC switch (9) is configured to switch the power supplied by the third capacitor bank (8) to the first amplifier (4) or the second amplifier (5). Therefore, a multi-channel RF transmit system (1) is disclosed where parts of the total available capabilities of discrete stored energy can be directed to one or the other RF amplifier channel (18, 19) leading to a more effective and cost saving design of the DC power supply chain.
