Through simulation of the real process of thomcolumbar burst fracture and use of modem dynamics techniques, the present study was (1) to investigate the kinetic relationship between structural damage and impact energy absorption and dynamics mechanism of thoracolumbar burst fracture by quantitative analysis of various injured segments;(2) to explore the instability mechanism of L1 vertebral burst fracture and its injury threshold by three-dimensional analysis of the injured segment with stereophotogrammetry in combination of transient physical parameters, anatomy and image;(3) to explore the corresponding relationships between impact energy, geometry parameters and biomechanics by geometry and biomechanical analysis of thoracolumbar burst fracture, which may provide an objective standard for evaluation of spinal injury severity and experimental evidence for adoption of biomechanical treatment in clinic;(4) to evaluate the fixation effect of different instruments and the effect of intervertebral bone graft on segment fixation by analysis of the threedimensional stability of different internal fixation instruments and their decompression of the spinal canal, which may provide experimental evidence for therapeutical selection for thoracolumbar burst fracture in future; and finally to investigate the effect of various instrument fixation on dynamical characteristics by comparison and quantitative analysis of frequency and amplitude responses, which may provide certain theories and experimental evidence for application of vibration test to judge the stability of the spine.

For image enhancement of digital radiography, the traditional processing methods originally used in various tomographic imaging modalities aren't available for enhancing the digital radiographic images, especially for the digital chest images because of the wide dynamic range of information between x-ray emerging from the heavily attenuated mediastinum (heart, spine, aorta, and other central features on the radiography) and subdiaphragmatic area and those that have passed through the air- filled lung.

对于数字放射图象的增强，原先用于CT等各种断层医学数字图象的传统处理方法并不能获得满意的效果，尤其对于数字放射胸片图象。其原因在于放射胸片图象具有相对较宽的信息动态范围，从具有非常大吸收系数的纵隔区（放射上指脊柱，心脏，主动脉）及下隔膜区到X线极易穿透的充满空气的肺部。
