Gradient induced heating of an AIMD is a serious safety hazard. To examine this risk a time consuming temperature mapping of the device with temperature probes is necessary to characterize hotspots on the implant. The use of IR cameras would directly point out where those hotspots occur and simplify those measurements to fewer mapping runs with temperature probes. But the small solution medium layer heights necessary for imaging could alter the hotspot characteristics. We investigated this problem with a laboratory test system and showed that hotspots neither move nor are affected in its location by different media types.
