Gradient induced heating is relevant for RF coils used in recent high-performance gradient coils. In this abstract, we investigate the predictability of gradient induced heating on the basis of theoretical gradient field data. Furthermore, the heating of components usually used for coil construction e.g. different plugs, cables and shielding materials under intense gradient usage (EPI readout with 100 mT/m and 1200 mT/m/s at almost 100% duty cycle for 1 min) was measured. Depending on the position and orientation we observe temperature increases up to 67°C for an N-plug and 12°C for a coaxial cable.
