Abstract
A magnetic resonance imaging apparatus according to an embodiment includes a monitoring coil, a measuring device, and processing circuitry. The monitoring coil continuously transmits to a subject an electromagnetic wave having a monitoring frequency, and without touching the subject. The measuring device measures a change in the impedance related to the monitoring coil over time to thereby generate a biosignal of the subject. The processing circuitry is configured to determine the monitoring frequency that is higher than a frequency of a high-frequency magnetic field based on the information of the subject, and to controls a sequence related to the imaging based on the biosignal.
