"X-ray filming is even today effectively the only imaging technique that allows all the most important speech articulators (jaw, tongue, lips, soft palate, larynx) to be captured in a single view at a framerate that is reasonably adequate for speech. However, in most countries it is no longer considered ethically acceptable to make cineradiographic recordings of speech with healthy subjects, unless there is some clear clinical indication for the recordings. Thus existing x-ray films form an irreplaceable source of information on speech."
