We demonstrate that the maximum SAR-induced temperature in an examination can be lowered with strategic ordering of the sequences in the exam. Using numerical simulations, here we optimize the order of and time between sequences in a spine exam to minimize the maximum temperature reached in a human body model without increasing the duration of the exam. The optimized sequence has a maximum temperature 0.63 C lower than the original.
