Abstract
According to one embodiment, a MRI apparatus includes an RF coil apparatus receiving MR signals by coil elements corresponding to channels, modulating the MR signals to have different frequencies for each of the channels, and outputting an analog multiplexed signal in which the MR signals with different frequencies are composited over the channels, and a receiver including ADC circuitry converting the analog multiplexed signal to a digital multiplexed signal, and predetermined number of separation channels separating the digital multiplexed signal, based on the number of the channels relating to composition of the MR signals with the different frequencies. The receiver stops a separation process of the digital multiplexed signal for separation channels not used in the separation process among the predetermined number of separation channels.
