Conversation device of MR imaging apparatus

Claim 1

A magnetic resonance imaging apparatus provided with a conversation device, comprising: a magnet for generating a static magnetic field; a gradient field coil disposed between a pair of pole pieces of the magnet for generating a gradient magnetic field, the gradient magnetic field being used for endowing a nuclear magnetic resonance signal with positional information; high-frequency transmitting and receiving coils disposed in the gradient field coil for transmitting an electromagnetic wave and for detecting the nuclear magnetic resonance signal, respectively; means for forming a magnetic resonance image based on the nuclear magnetic resonance signal; bed means, disposed in the high-frequency transmitting and receiving coils, for holding a person to be inspected by the magnetic resonance imaging apparatus; an auxiliary member mounted on the bed means for keeping a portion of the to-be-inspected person in a predetermined position on the bed means; and a communication system for realizing a conversation between the to-be-inspected person and an operator of the magnetic resonance imaging apparatus, the communication system including: a bone conduction microphone mounted on the auxiliary member so that the bone conduction microphone can be kept in contact with that portion of an upper half part of the to-be-inspected person which can conduct the voice of the to-be-inspected person by a bone, the bone conduction microphone being substantially insensitive to a magnetic field and surrounding noise.
