报告内容简介: In the field of orthopedic biomechanics, geometry, alignment, and movement of the anatomic structure and material properties of the tissues are the common parameters in making a diagnosis and planning treatment. Medical imaging has been a useful tool for possible non-invasive examination. Commonly used imaging techniques consist of x-ray radiography, fluoroscopy, computer tomography, ultrasound, and magnetic resonance imaging. For measuring skeletal motion and the migration of artificial implants, bi-planar stereo radiography has been developed and used. More recently, methods have been developed for registering three-dimensional models to single plane x-ray fluoroscopy images. CT and MRI are available for assessing the skeletal movement based on imaging registrations and animation. For the assessment of the internal stress and deformation of the musculoskeletal system, the 3D CT scan enables the finite element mesh generation of the internal structure. Applications of the speckle tracking in US and texture or block matching in MRI images enable mapping of deformation and strain fields of the soft tissue. Material properties, such as the modulus and strength of bonehave been quantified by using quantitative CT. Furthermore, elastography based on US and MRI enables the quantification of material properties of soft tissue. In summary, medical imaging provides useful tools for assessing biomechanical parameters of the musculoskeletal system. These technologies are essential for enhancing diagnoses in orthopedicsand monitoring the success of the tissue regeneration in the application of tissue engineering.
