Popis: MRI enables the in vivo analysis of the three-dimensional functional anatomy of the human vocal tract during phonation. For this purpose, MRI examinations are performed during phonation using different slice orientations. Subsequent anatomically correct registration enables a high-precision three-dimensional reconstruction of the vocal tract. Finally, a curvilinear midline is computed from which the threedimensional functional anatomy of the human vocal tract can be approximated by a cascade of cylindric objects represented by their characteristic location-dependent cross-sectional areas (“area function”).
