摘要

A gated amplifier 32 drives a gradient coil 25 when the gate signal 31 is applied and the gate signal 31 also controls an FET switch 30 to disconnect a shim power supply from shim coils 23 and connects the shim power supply instead to a dummy load. When the gate signal 31 is removed, the shim coil 23 is restored to operation from the shim power supply. IMAGE
