Magnetic resonance imaging apparatus, signal selection method in magnetic resonance imaging apparatus, and magnetic resonance imaging method in magnetic resonance imaging apparatus

A magnetic resonance imaging apparatus of processing and imaging some of magnetic resonance signals corresponding to a plurality of channels, comprising:

• a first converter that converts some of the magnetic resonance signals, to be processed, corresponding to the plurality of channels into signals corresponding to a plurality of effective channels set within a first frequency band and converts magnetic resonance signals corresponding to other channels into signals corresponding to channels set within a second frequency band different from the first frequency band;
• a synthesizer that synthesizes the channel-converted signals;
• and
• a reconstruction unit that reconstructs an image on the basis of a signal, included in the first frequency band, of the synthesized signals.

• extracting a signal included in the first frequency band from the synthesized signals;
• and
• dividing the extracted signal into magnetic resonance signals corresponding to the plurality of effective channels.
