Dynamic simulation of alveolar bone remodeling is important for orthodontic study and clinical operation, but dynamic simulation based on tissue change has never been realized. Based on a remodeling model obtained from data in literature, using a viscoelastic constitutive model of periodontal ligament obtained by experiment data fitting, the alveolar remodeling progress was simulated with a program...
The purpose of this study was to explore the automatic method of detecting the gray matter loss of Alzheimerpsilas disease (AD) patients with magnetic resonance imaging (MRI). In this paper, voxel-based morphometry (VBM) and support vector machine (SVM )were combined and introduced to diagnose Alzheimer's disease(AD) for clinical applications. Firstly, with the VBM method, 20 features were obtained...
The purpose of our study was to explore the automatic method of detecting the gray matter loss of Alzheimer's disease (AD) patients with magnetic resonance imaging (MRI). In this paper, we tried to combine voxel-based morphometry(VBM) with Artificial Neural Network(ANN) in diagnosing Alzheimer's disease(AD). Firstly, the features were obtained by VBM method, and then principal component analysis(PCA)...
