Abstract
An RF coil device and an MRI apparatus allowing a connection relationship between input RF channels and output RF channels to be controlled by a smaller number of switch elements are provided. The RF coil device includes multiple coil segments and a multi-selection switch. Input terminals of the multi-selection switch are each connected to a different coil segment. An output terminal of the multi-selection switch leads to an RF output channel. A control terminal of the multi-selection switch is used to receive a control signal so as to select a coil segment for connection to the output terminal. Multiple coil segments connected to the input terminals are not in consecutive positions, and the number of coil segments by which any two of the multiple coil segments are spaced apart is no fewer than the maximum number of coil segments required for one MRI imaging less 1. The MRI apparatus includes the RF coil device.
