摘要： PROBLEM TO BE SOLVED: To solve such the problem that though the resolution of MRI is improved by increasing power of RF (electromagnetic waves) since the RF coil of an MRI apparatus is installed on the inner side of a static magnetic field coil and a gradient magnetic field coil, and a living body is irradiated with the RF in order to obtain nuclear magnetic resonance signals, the potential of the RF coil becomes high when the power of the RF is increased, and thus a structure of sticking a conductor in an arbitrary shape to a hollow cylindrical insulator or the like is formed in order to arrange the RF coil around the living body, but the insulator needs to be thick since the potential becomes high also on the inner side wall surface of the cylindrical insulator when the potential of the RF coil becomes high and a space where the living body enters becomes narrow.SOLUTION: By installing an electrostatic shield and a groove or a hole filled with air or an insulator of a low dielectric constant to an RF coil insulator, an MRI apparatus having an insulation structure of an RF coil capable of increasing RF power without excessively increasing the thickness of the insulator is provided.
