发明名称 Magnetic resonance imaging (MRI) diagnostic apparatus capable of optimally controlling radio-frequency magnetic field by providing flexible material interposed between RF coil and body
摘要 A magnetic resonance imaging (MRI) diagnostic apparatus capable of eliminating density inhomogeneity of the tomographic images obtained thereby. The MRI diagnostic apparatus includes a gantry for defining a space for a MRI diagnosis; an RF shield, disposed inside the gantry and outside an RF coil; and material for correcting a distribution of an RF magnetic field at the time of RF transmitting or receiving by the RF coil, wherein the field correcting material is interposed between the biological body lying inside the shield and the RF coil. Preferably, the field correcting material includes an aqueous high-molecular gel sheet which is flexibly deformable along the shape of the biological body.
