Patent ID: 6859035

Claim:
A magnetic resonance imaging apparatus comprising a gantry whose structural components include: a static field magnet, a gradient field coil, a high-frequency coil, and a sealed vessel that houses the gradient field coil, and wherein at least one of the structural components of the gantry which is formed by one of the static field magnet, gradient field coil, high-frequency coil and sealed vessel is coupled together with another one of the structural components of the gantry which is formed by another one of the static field magnet, gradient field coil, high-frequency coil and sealed vessel at least partially with attachment screws such that: (a) where electric connection is require, coupled structural components of the gantry are in metallic contact with one another, and attachment screws are prevented from being in metallic contact with the joined structural components, and (b) where physical fixing is required but electrical connection is not required, coupled structural components of the gantry and attachment screws are prevented from being in mutual metallic contact with one another.
