Abstract
An MRI apparatus excellent in magnetic field generation efficiency is provided. According to this invention, a main coil () of a gradient magnetic field coil () is partially recessed to reduce the total thickness of a radio-frequency coil () and a gradient magnetic field coil (). That is, the main coil () is designed in a tubular shape, and the diameter rat the center portion of the imaging space is larger than the diameter rof the main coil end portion. Accordingly, the RF coil () can be disposed to be near to the gradient magnetic field coil () side without lowering the magnetic field generation efficiency.
