Název v původním jazyce

Numerical reconstruction of the videokymography records-sensitivity of the computational model

Popis výsledku v původním jazyce

Three-dimensional (3D) finite element (FE) fully parametric model of the human larynx was developed and used for numerical simulation of vibration of the vocal folds with collisions. The vocal fold tissue was modeled as a three layered transversal isotropic material. It is shown that taking into account the superficial sublayer inside the lamina propria with liquid like properties the mucosal waves are more clearly modeled in the medial cross-section of the vocal folds. The waves are comparable with themucosal waves observed in humans by videokymography or digital kymography used for visualization of the vibratory pattern and also measured on excised larynges and physical vocal folds models. The videokymography records are reconstructed from the numerical simulation of the vocal fold vibrations for different material configuration of the separate layers.
