Gradient coil arrangement for magnetic resonance equipment, has pipe-shaped shielding cylinder connected firmly with gradient coil system or is an integral mechanical component of gradient coil system

摘要

A pipe-shaped shielding cylinder is arranged surrounding the gradient coil system in the orifice of main field magnetic system and surrounded by main field magnetic system. The shielding cylinder is connected mechanically firmly with gradient coil system or is an integral mechanical component of gradient coil system to shield gradient coil system actively.
