ABSTRACT:
Disclosed is a magentic resonance imaging apparatus which comprises a transmission probe head, a reception probe head, and inclined magnetic field coil means. The transmission probe head applies a high-frequency magnetic field to a subject, while the reception probe head receives magnetic resonance signals from the subject. The inclined magnetic field coil means generates and applies an inclined magnetic field to the subject. If the inclined magnetic field is applied to the subject, the magnetic resonance signals detected by the reception probe head are provided with generative position information. An electromagnetic coupling prevention member is interposed between the coil means and the transmission and reception probe heads. The prevention member includes a plurality of high-conductivity portions and a plurality of electrically discontinuous portions electrically separating the high-conductivity portions from one another.
