    摘要: A magnetic resonance imaging apparatus according to an embodiment includes a Radio Frequency (RF) coil configured to apply an RF magnetic field to a subject. The RF coil includes: a supporting member formed to have a circular cylindrical shape; and an electrically-conductive member which is arranged to extend along an axial direction of the supporting member and through which a radio frequency current flows when the RF magnetic field is generated. The electrically-conductive member includes: a first part provided on an outer circumferential surface of the supporting member; and a second part positioned farther away from an RF shield provided on an outer circumferential side of the RF coil than the first part is, in terms of a radial direction of the supporting member.

    摘要: A magnetic resonance imaging apparatus according to an embodiment includes a Radio Frequency (RE) coil configured to apply an RF magnetic field to a subject. The RF coil includes: a supporting member formed to have a circular cylindrical shape; and an electrically-conductive member which is arranged to extend along an axial direction of the supporting member and through which a radio frequency current flows when the RF magnetic field is generated.
