Quality assurance and radiofrequency heating.
This paper proposes an inexpensive means of assessing radiofrequency (RF) power deposition in a magnet. This is particularly important at 3T where sequences approach Food and Drug Administration approved RF limits. It will also be of interest to operators at 1.5 T as part of their ongoing quality assurance programs. At 3T, we found that the RF power deposited in the magnet was less than that read by the MR power monitor.
