(a) A montage of nine individual PCXI images from the pilot ex vivo experiment that examined an excised mouse trachea. The images were taken after all five particulates had been delivered within individual 15 µl boluses. All five particle types are clearly visible and marked. (b) An in vivo montage of 15 individual PCXI images with the ET tube uppermost in the trachea. The ET tube opening is approximately two cartilage rings from the top, and the standard imaging location, usually three rings below the bottom of the ET tube, is marked with a white rectangle. Dark particles of galena are apparent within the ET tube as well as at the imaging site in the trachea. Image alignment is poor at some montage frame edges owing to respiratory movements that occurred between image captures.
