Fig. 7From: High-resolution mucociliary transport measurement in live excised large animal trachea using synchrotron X-ray imagingParticle tracking at the pig carina. Particles could also be successfully tracked at the pig carina. In this sample the presence of the bubbles on the airway surface increased the false positive detection rate. Additional file 3: Video S3 shows the tracking results for this sample. Scale bar 2 mmBack to article page
