摘要：

Magnetic resonance imaging (MRI) is more and more widely used in clinic. How to ensure the safety of MRI examination for patients with active implantable medical devices is an urgent problem to be solved. This study developed a radio frequency (RF) transmit coil and built a RF magnetic field test platform at 64 MHz for the magnetic resonance compatibility evaluation of active implantable devices. As a result, the RF transmit coil can withstand a high input peak power, up to 15 kW, which can be used for RF thermal test, RF field instrument failure test and RF rectification test of the active implantable medical devices.
