MAGNETIC RESONANCE IMAGING APPARATUS AND RF COIL DEVICE

摘要

According to one embodiment, an MRI apparatus (20) includes a first RF coil device (700), a radio communication unit (640) and an image reconstruction unit (56). The first RF coil device is wirelessly connected to a second RF coil device (800), and receives a nuclear magnetic resonance signal wirelessly transmitted from the second RF coil device. The first RF coil device wirelessly transmits the nuclear magnetic resonance signal detect by the first RF coil device and the nuclear magnetic resonance signal obtained from the second RF coil device to the radio communication unit, via an induced electric field. The radio communication unit receives the nuclear magnetic resonance signals wirelessly transmitted from the first RF coil device via an induced electric field. The image reconstruction unit reconstructs image data on the basis of the nuclear magnetic resonance signals received by the radio communication unit.
