The goal of this study was to develop a computational model that can accurately predict the radiofrequency (RF) induced temperature rise of medical devices in a 1.2T (49 MHz) Hitachi Oasis open bore system for the purpose of MRI labeling according to ASTM F2503. A comparison of experimental and analytical temperature rise of calibration rods, a stent, and a knee implant within a gel phantom was conducted. Simulations of RF heating of the stent and knee implant within the Duke virtual human model were compared for the 1.2T Hitachi Oasis open bore and 1.5T Siemens Avanto closed bore MRI systems.
