Abstract
A radiofrequency antenna has a plurality of channels. A Q-value calculating unit computes reflected signals of the plurality of channels of the radiofrequency antenna, respectively, in a case where transmission signals as electrical signals are simultaneously supplied to the plurality of channels of the radiofrequency antenna, also including a signal obtained when the transmission signal supplied to one channel of the plurality of channels is reflected from another channel, and computes a Q value of the radiofrequency antenna using the reflected signal. An SAR calculating unit calculates a specific absorption rate (SAR) using the Q value.
