ABSTRACT:
A transmitting/receiving system for use in a magnetic resonance imaging system includes a first coil section used for both transmission and reception, a transmitter for transmitting a high-frequency field for exciting a magnetic resonance phenomenon to an object through the first coil section, a first receiver which constitutes a first resonator, capable of resonating with a magnetic resonance signal from the object, together with the first coil section, for receiving the magnetic resonance signal through the first coil section, a second coil section used for reception, and a second receiver which constitutes a second resonator, capable of resonating with the magnetic resonance signal from the object, together with the second coil section, for receiving the magnetic resonance signal through the second coil section. Either the first or second receiver is selectively used. When the second receiver is enabled, a resonance condition of the first resonator is changed to suppress resonance of the first resonator with respect to the magnetic resonance signal.
