MAGNETIC RESONANCE IMAGING APPARATUS |
| 摘要 |
In one embodiment, an MRI apparatus includes a wireless RF coil; a control side oscillator configured to output a control-side clock signal used for executing a pulse sequence; and a synchronization signal transmission circuit configured to wirelessly transmit a synchronization signal to the wireless RF coil in an executing period of the pulse sequence, except an MR-signal detection period during which the wireless RF coil detects a magnetic resonance signal, wherein the synchronization signal is within a frequency band of a Larmor frequency and reflects a phase of the control-side clock signal. |
