In this work we propose utilization of a very low amplitude, rectangular and off-center RF pulse applied during echo detection, LARFET (Low Amplitude RF at Echo Time), that can be used as the reference for frequency downconversion at the catheter tip. With frequency downconversion the signal losses during transmission are lowered and the frequency analysis to extract the location information is simplified.
