Abstract
A system for validating safety of a medical device in a presence of a magnetic resonance imaging (MRI) field is provided. The system includes a first electric field generating device configured to form first electric field and configured to receive a medical device at least partially within the first electric field, and a second electric field generating device configured to form a second electric field in proximity to the first electric field and configured to receive the medical device at least partially within the second electric field. One or more processors are configured to execute program instructions to calculate predicted parameter values of the medical device based on a transfer function, the transfer function defined to predict a safety characteristic of the medical device when in the presence of an MRI field, obtain measured parameter values from the medical device, the measured parameter values indicative of the safety characteristic of the medical device when exposed to the first and second electric fields, and compare the measured parameter values to the predicted parameter values in connection with validating the transfer function.
