Abstract
In a system, apparatus and method for achieving scanning safety for a magnetic resonance conditionally safe implant, an FPO processor converts an RF power signal received from an RF power sensor of an MR scanner into an RF power parameter, and converts a gradient power signal received from an MR gradient power sensor of the MR scanner into a gradient power parameter. Upon detecting that the RF power parameter exceeds an RF power limit value or/and the gradient power parameter exceeds a gradient power limit value, the FPO processor sends a shutdown signal, to shut down an RF power amplifier or/and a gradient power amplifier in the MR scanner. The MR scanner is thereby enabled to realize the FPO mode, without altering MR scanner software, and the workload is small and easy to carry out.
