Teeth are almost invisible in magnetic resonance imaging (MRI) because they lack free
protons to magnetically react. In MRI-based studies on the vocal tract, the teeth must be
visualized on the volume data obtained during articulation. To do so, varieties of techniques
have been proposed, either covering the teeth by opaque materials or obtaining tooth
images followed by their superimposition. In this article, a new method was proposed to
visualize the teeth in vowel production MR images for the application of three-dimensional …
