This work presents a cost-effective near-field RF mapping approach for accurate tracking of a field probe. The method is based on the OpenCV library. It serves as a practical tool for the rapid assessment and characterization of MR coils and arrays. The only equipment required for the setup is a field probe, a regular webcam, and a paper QR code label, which renders this technique highly accessible and easy-to-use.
