Accurate localization of the anatomical landmarks on distal femur bone in the 3D medical images is very important for knee surgery planning and biomechanics analysis. However, the landmark identification process is often conducted manually or by using the inserted auxiliaries, which is time-consuming and lacks of accuracy. In this paper, an automatic localization method is proposed to determine positions...
As a minimally invasive surgery to treat atrial fibrillation (AF), catheter based ablation uses high radio-frequency energy to eliminate potential sources of abnormal electrical events, especially around the ostia of pulmonary veins (PV). Fusing a patient-specific left atrium (LA) model (including LA chamber, appendage, and PVs) with electro-anatomical maps or overlaying the model onto 2-D real-time...
The relationship between economic development and enviroment quality has become a big concern for the world, especially for developing countries. This paper, taking Shaanxi in west region as an example, analyzed the relationship between economy and enviroment through the Enviromental Kuznets Curves(EKC). The result showed that the relationship between economic development and enviroment not only takes...
We propose a simple and effective modeling method for creating animation opening flowers. Because the detailed geometry of flower petals is defined by a base shape deformation, we simulate the development of petal based on deformation and emulate its growth by change the deformation parameters. The structural arrangement of flower petals is established by the L-system that produces natural looking...
With the promotion of the electroporation therapy clinical application, how to design an electrode with a lower voltage level and distribution and high intensity electric field in order to achieve the optimal treatment of tumors. In this paper, FEMLAB finite element analysis software is used for the needle electrodes in biological tissue electroporation for electric field simulation, the simulation...
In recent years, the young and expanding research community of granular computing has begun to show interest in image processing, specifically in the area of image retrieval from image databases or the Web. It might therefore be beneficial to provide a background to researchers in granular computing, at a reasonable depth, of the techniques employed in image retrieval, particularly in the case of...
