Computational modeling of RF-induced heating due to a titanium-alloy rod was conducted by nine independent institutions with a primary goal to compare the impact of common, independent modeling choices on temperature rise results. Results showed that when the rod is located 2 cm from the enclosure, the temperature rise can be used to estimate the local background electric-field exposure. Temperature rise depends not only on the background exposure but also on the location of the rod within the phantom.
