We have undertaken the design and testing of a system for making measurements of velopharyngeal function from lateral videofluoroscopic images based upon standard equipment found in any cleft clinic. The uncertainties in the measurements have been found to be acceptably low and, in conjunction with other measurement techniques, the system has made a valuable contribution to the assessment of velopharyngeal function. Additional measurements using this system are presently being developed.
