Patient-Specific Modeling of the Cardiovascular System

This work offers a detailed overview of advanced patient-specific biomechanical modeling in cardiovascular medicine, emphasizing computational techniques for precise, individualized treatment strategies. The book explores finite element analysis, myocardial stress modeling, and aneurysm biomechanics, underscoring their clinical significance in enhancing diagnosis, management, and therapeutic outcomes for cardiovascular diseases.

Total Knee Replacement Polyethylene Stresses During Loading in a Knee Simulator

This study used finite element models to investigate the stresses and kinematics of a total knee replacement within a knee simulator. The researchers applied flexion/extension and various loadings to the components to mimic the simulator's conditions. They found that changing the stiffness of a spring-loaded bumper system had a minimal effect on both the joint's kinematics and the stresses on the polyethylene tibial component, which is useful for predicting wear in future research.

Recent Development on Computer Aided Tissue Engineering

Wei Sun, Pallavi Lal

Computer-aided tissue engineering (CATE) is a field that uses computer technology, such as imaging and computer-aided design (CAD), to create and manufacture biological scaffolds. These technologies help with surgical planning, anatomical modeling, and the 3D reconstruction of tissues for repair and replacement.

A Three-Dimensional, Anatomically Detailed Foot Model

A detailed 3-D reconstruction of a human foot was created from CT images, including individual bone meshes, soft tissue, and cartilage. Principal axes and relative angles of bones were calculated to quantify foot shape and provide an anatomical basis for future finite element modeling.

Finite Element Modeling of the Human Thoracolumbar Spine

This study developed a new finite element modeling technique to accurately predict the biomechanical properties of human vertebrae. By calibrating the model's shell properties to experimental data, the researchers created a reliable tool for studying vertebral behavior and improving clinical fracture risk assessments.
