Abstract
An object of the present invention is to intensify the strength of a magnetic field to be applied to a subject. An auxiliary coil is interposed between a body coil incorporated in a magnet assembly included in an MRI apparatus and the subject. When RF pulses are transmitted from the body coil, an induced current flows through the auxiliary coil and generates a magnetic field. The magnetic field excites the subject near the subject.
Claims10
An RF transmission method of using a magnetic field, which is generated by a current induced in an auxiliary coil interposed between a transmitter coil included in an MRI apparatus and a subject, by RF pulses sent from the transmitter coil to excite the subject.
An MRI apparatus comprising a transmitter coil that transmits RF pulses, and an auxiliary coil that is disposed nearer the subject than the transmitter coil and excites a subject using a magnetic field generated by a current induced by the RF pulses.
An auxiliary coil that is interposed between a transmitter coil included in an MRI apparatus and a subject and that excites a subject using a magnetic field generated by a current induced by RF pulses sent from the transmitter coil.
