IEEEAbstract—Ciliary movements within the human airwayare essential for maintaining a clean lung environment.Motile cilia have a characteristic ciliary beat frequency(CBF). However, CBF measurement with current videomicroscopic techniques can be error-prone due to the useof the single-point Fourier transformation, which is oftenbiased for ciliary measurements. Herein, we describe anew video microscopy technique that harnesses a met-ric of motion-contrast imaging and image correlation forCBF analysis. It can provide objective and selective CBFmeasurements for individual motile cilia and generate CBFmaps for the imaged area. The measurement performance ofour methodology was validated within vitrohuman airwayorganoid models that simulated an actual human airwayepithelium. The CBF determined for the region of inter-est (ROI) was equal to that obtained with manual counting
