A new method to validate the transfer function (TF) of linear implants was developed, using an independent RF transmitter. A simulation study was performed exploring different methods to change the incident electric field, local transmit coils positioned at various locations is most effective for the validation. A benefit is the constant position of the leap tip and the temperature probe. We performed a TF measurement and validation study for three leads. The simulated incident electric fields of the local transmit coils and the measured TF were used to predict tip heating, verified by temperature probe measurements showing excellent agreement ($$$R^2\geq0.977$$$).
