We have previously proposed Beat Pilot Tone (BPT), a motion sensing method using ultra-high-frequency RF and preamplifier intermodulation. BPT uses ultra-high-frequencies, which provides greater sensitivity to motion compared to the Pilot Tone (PT). In this work, we use the motion estimates from the BPT to reconstruct respiratory and cardiac-resolved images and compare them to motion-resolved images obtained using PT, respiratory bellows, and electrocardiogram (ECG) data. We show that BPT provides comparable image quality to conventional motion sensing for respiratory and cardiac motion.
