MRI apparatus includes an RF coil device, a first radio communication unit, a second radio communication unit, an image reconstruction unit and a judging unit. The RF coil device detects an MR signal, and includes a data saving unit for storing the MR signal. The first radio communication unit wirelessly transmits the MR signal detected by the RF coil device, and the second radio communication unit receives the MR signal from the first radio communication unit. The image reconstruction unit reconstructs image data using the MR signal. The judging unit judges existence of a transmission error in radio communication between the first and second radio communication units. If the transmission error is present, the first radio communication unit wirelessly transmit the MR signal stored in the data saving unit to the second radio communication unit.

Magnetic resonance imaging apparatus

MRI apparatus includes a first radio frequency (RF) communication unit, a second RF communication unit, an image reconstruction unit and a table for loading an object. The first RF communication unit obtains a nuclear magnetic resonance (NMR) signal detected by an RF coil device, and wirelessly transmits a digitized NMR signal via an induced electric field. The second RF communication unit receives the NMR signal via the induced electric field. The image reconstruction unit reconstructs image data based on the NMR signal. The table includes a supporting unit which detachably supports the first RF communication unit to the second radio communication unit so that an interval between the first and second RF communication units enables RF communication via the induced electric field.

Magnetic resonance imaging apparatus, bed device and RF coil device

In one embodiment, an RF coil device includes a base board, a belt member, a first coil element, a second coil element inside the base board, and a connecting unit. Both ends of the belt member are respectively connected to mutually separated places on the base board, so that the center part of the belt member is located on the anterior surface of the base board. The belt member is curved to form airspace between the center part thereof and the anterior surface for letting an arm pass through in interdigitation state. The first coil element includes first and second partial coils inside the belt member, and becomes a loop coil element by their connection. The connecting unit detachably connects the base board to the belt member, and mutually connects the first and second partial coils in the interdigitation state.

RF coil device and magnetic resonance imaging apparatus

A receiving RF coil includes a coil element group having a figure-eight coil, a first loop coil arranged at the center of the figure-eight coil, and a second loop coil partially overlaid on the first loop coil. Furthermore, a path switching control unit switches the transmitting paths of a signal so that the signal can be received and/or transmitted with a combination of the first loop coil and the second loop coil or a combination of the figure-eight coil and the first loop coil.
