Morfometria do trato vocal por ressonância magnética: simulação de padrões patológicos articulatórios

Abstract

Introduction - The shape or morphologic analysis of anatomical struc‑ tures, such as the vocal tract can be performed from two‑dimensional (2D) or volume‑ tric acquisitions (3D) of magnetic resonance imaging (MRI). This imaging technique has had an increasing use in the study of speech production. Objectives - To deter‑ mine a method to perform the morphometric analysis of the vocal tract from magnetic resonance imaging; to present anatomical patterns during the normal speech produc‑ tion of some vowels and two pathological articulatory disorders in simulated context. Methods - The image data was collected from 2D (Turbo Spin Echo) and 3D (Flash Gradient Echo) acquisitions of MRI of four subjects during the production of three vowels; in addition, two articulatory disorders were assessed using this imaging proto‑
