Abstract

A gradient coil system for a magnetic resonance apparatus has gradient coils and at least one cooling tube for cooling the gradient coils using a coolant flowing through the cooling tube. The cooling tube is formed of a flexible thermoplastic material, augmented with a filler, and has a thermal conductivity greater than 0.5 W/mK.
