The ability to accurately calculate the induced current distribution, caused by gradient switching, over arbitrary thin conducting surfaces is extremely useful for the design and MR safety evaluation of medical devices and interventional robotics. In this abstract we present an integral method to calculate these induced currents. The method is applied to predict the average heating rate of a thin conductor and then extended to calculate the spatial distribution of power deposition over the conductor surface and subsequent spatially varying heating rate.
