The influence of muscles activation on the dynamical behaviour of the tympano-o...

Gentil, F; Parente, M; Martins, P; Garbe, C; Paço, J; Ferreira, AJ; Tavares, JM; Jorge, RN

The human ear is a complex biomechanical system and is divided into three parts: outer, middle and inner ear. The middle ear is formed by ossicles (malleus, incus and stapes), ligaments, muscles and tendons, which transfers sound vibrations from the eardrum to the inner ear, linking with mastoid and Eustachian tube. In this work, a finite element modelling of the tympano-ossicular system of the middle ear was d...

Analysis of eardrum pathologies using the finite element method

Gentil, Fernanda; GARBE, CAROLINA; PARENTE, MARCO; MARTINS, PEDRO; FERREIRA, ANTÓNIO; JORGE, RENATO NATAL; SANTOS, CARLA; PAÇO, JOÃO

This work investigates the effect of eardrum perforations and myringosclerosis in the mechanical behavior of the tympano-ossicular chain. A 3D model for the tympano-ossicular chain was created and different numerical simulations were made, using the finite element method. For the eardrum perforations, three different calibers of perforated eardrums were simulated. For the micro perforation (0.6 mm of diameter) ...


Segmentation algorithms for ear image data towards biomechanical studies

Ferreira, Ana; Gentil, Fernanda; Tavares, João Manuel R. S.

In recent years, the segmentation, i.e. the identification, of ear structures in video-otoscopy, computerised tomography (CT) and magnetic resonance (MR) image data, has gained significant importance in the medical imaging area, particularly those in CT and MR imaging. Segmentation is the fundamental step of any automated technique for supporting the medical diagnosis and, in particular, in biomechanics studies...
