Application of radiological dynamic imaging for rehabilitation medicine

我们为康复医学开发了一种新的肌肉、骨骼、关节运动和心肺功能的动态X线片。胸部检查时，拍摄从吸气到呼气的连续胸片，分析肺部局部密度的变化，以发现呼吸异常。对于肩、腕、膝等四肢关节，在屈曲、伸展或旋转运动时拍摄连续的X线片，并对其运动角度和部分骨外倾角进行定量分析。通过与MRI、US和核医学影像的对比研究，这些影像技术和定量分析可用于动态胸部检查和肌肉痉挛检查，以评估康复疗效。

We have developed a new dynamic radiographies of muscle, bone, joint movements, and cardiopulmonary function for rehabilitation medicine. For chest examination, the sequential chest radiographs from inspiration to expiration were taken and analyzed the density changes at local area in lung to detect respiratory anomalies. For limb joints, such as shoulder, wrist, and knee, the sequential radiographs during flexion and extension, or rotational movement were taken and analyzed the movement angle and some hone ectopias quantitatively. According to comparing investigations with MRI, US, and Nuclear medicine imaging, these imaging techniques and the quantitative analysis are useful for dynamic chest examination and musculoskeltal examinations for the evaluation of rehabilitation efficacy.
