Abstract: Disclosed herein is a coil component that includes plural conductor layers embedded in the magnetic element body. Each of the conductor layers includes a coil pattern, and first and second connection patterns exposed from the magnetic element body. The conductor layers includes a first conductor layer positioned at one end portion in the stacking direction, a second conductor layer positioned at the other end portion in the stacking direction, and one or more third conductor layers positioned between the first and second conductor layers. In the second conductor layer, an outer peripheral end of the coil pattern is connected to the second connection pattern through a lead-out pattern. In at least one of the first to third conductor layers, the magnetic element body is disposed in a separation area overlapping the lead-out pattern in the stacking direction.

Abstract: 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.

Abstract: 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.

Abstract: 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.
