The proposed approach does not require any additional imaging protocols to be performed and pTx vector optimizations can be calculated solely e.g. based on low-cost sensors embedded in implants. The methodology was tested on a custom-built sensor-equipped wireless implant in 3T MRI experiments and realistic DBS lead configurations.
