Synopsis

Keywords: Safety, Safety, Implants, RF-induced heatingThe novel open 64 MHz linear exposure system offers new possibilities for the test process of active implants for RF-induced heating as a safety issue. This study proves the concept, that the measurements for the validation process of the transfer function, which models the electric behavior of an active implant, could be accelerated from hours of precise work to minutes without any rearranging. Because the system is open, there is significantly more space than in a birdcage coil and the object and measuring probe can be mounted to a movement system, that can access the whole phantom.
