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. MITS1.5 is compatible with the latest draft of the ISO/IEC standard for Active Medical Implant Devices. The system has been rigorously validated. A numerical model of the birdcage is provided. The system is supported by the DASY52NEO 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 DASY52NEO scanner. |
