RF-Heating Testing in 64 MHz RF-Laboratory System and 1.5 Tesla MRI a Comparative Evaluation

Wolfgang Grtz¹, Nicolas Flle¹, Gerrit Schnwald¹, Susanne Matthey¹, Gregor Schaefers¹

RF-heating tests as described in ASTM F2182 have been performed in a 1.5 Tesla MR scanner and additionally in a 64 MHz RF laboratory workbench system. A comparison of the results of the detected temperature increases shows a good agreement between both systems. Based on this finding it can be concluded that the laboratory system is an alternative to usually used clinical MR systems for RF heating test on medical implants following ASTM F2182.
