MITS1.5

Medical Implant Test System (MITS) for 1.5 Tesla RF Safety Evaluation

MITS1.5 is designed to simulate high-precision incident fields with user-defined modulation and time sequences as generated by commercial 1.5 Tesla magnetic resonance scanners (also enables worst-case incident field conditions). The system combines cutting-edge technology with accuracy, versatility and user-friendliness. The open user interface allows customized, automated evaluations.

Medical Implant Test System (MITS) for 1.5 Tesla operated in vertical mode.

 

MITS1.5 is compatible with the latest draft of the ISO/TS 10974 standard for Active Medical Implant Devices. The system has been rigorously validated. A Sim4Life numerical model of the birdcage is available.

The system is supported by the DASY AIMD scanner, from our sister company SPEAG for rapid and high precision SAR and temperature evaluations. However, MITS systems are standalone products and do not require the DASY AIMD scanner.
