Common Software for Modeling and Simulation and Its Mechanics Principle

Image data is very important for the diagnosis of many orthopedic diseases such as fractures and osteoporosis. Therefore, researchers and equipment manufacturers in related fields have developed many different methods to image bone tissue. For example, the technologie such asX-ray photography, computed tomography (CT), and magnetic resonance imaging (MRI) which are often used in clinical practice, as well as laboratory equipment such as micro-CT and micro-MRI, are all the ways to depict the geometric structure of human tissues in different degrees. And dual-energy bone densitometers and some new ultrasound equipment can image the distribution of functional parameters such as bone density. For the modeling and simulation of the human musculoskeletal system, 3D modeling is already the current mainstream modeling method. Therefore, the following mainly introduces several commonly used image acquisition methods for 3D modeling.
