Subject-Specific Modeling of Facial Mimics derived from MRI Data using FEM
نویسنده
چکیده
Resume — A muscle-driven model of human lower face was established. Three pairs of facial mimic muscles (ZM Zygomaticus Major, LLS Levator Labii Superioris, LAO Levator Anguli Oris), subcutaneous soft tissues, skin and skull were reconstructed based on segmentation of subject-specific MRI data. FE simulation were performed to reproduce designed facial mimic positions (e.g. pronunciation of sound /o/), with comparison to experimental measurements. Muscle was modeled as a transversely-isotropic hyperelastic material with autonomous contraction.

FEM investigation of drilling conditions on heat generation during teeth implantation
Abstract The first step of implanting teeth is to drill a hole in the jaw bone. Excessive temperature produced during drilling is one of the destructive factors for bony tissue. If the temperature generation during surgical drilling exceeds the critical temperature, it could lead to osteonecrosis. This research intends to study drilling parameters such as drilling speed, feed rate, cooling con...
متن کاملAn Improved Facial Orthopedic Surgery Planning System with Pre-processing FEM Modeling
Finite Element Method(FEM), which is based upon continuum mechanics and the physics of materials, is one of the most widely used deformation method in digital biomedical area. Unlike other light-weighted deformation models (Mass-Spring, Free Form, Chainmail, BEM, etc)using in other areas, FEM gets the most accurate deforming results in the cost of large scale of computation. In this paper, we p...
متن کاملFacial Modeling for Plastic Surgery Using Magnetic Resonance Imagery and 3D Surface Data
We describe a novel facial modeling and real-time pre-surgery planning + visualization tool for surgical and esthetic plastic surgery. The modeling pipeline accepts geometry both in the form of Magnetic Resonance Imagery (MRI) and/or 3D facial surface scans. The MRI data is first used to segment the skin surface as well as the underlying tissues of interest. Textures taken with a digital camera...
متن کاملStroke mimics in patients with clinical signs of stroke
Background: Stroke mimic is a major diagnostic challenge and may be difficult to distinguish from real strokes. The aim of this study was to evaluate the relative frequency of stroke mimics in patients with clinical signs of stroke. Methods: In this cross sectional-study, the medical records of 1985 patients with stroke admitted to Poursina Hospital were enrolled using the census technique. ...
متن کاملInter-Individual Variation during Transcranial Direct Current Stimulation and Normalization of Dose Using MRI-Derived Computational Models
BACKGROUND Transcranial Direct Current Stimulation (tDCS) is a non-invasive, versatile, and safe neuromodulation technology under investigation for the treatment of neuropsychiatric disorders, adjunct to rehabilitation, and cognitive enhancement in healthy adults. Despite promising results, there is variability in responsiveness. One potential source of variability is the intensity of current d...
