中文摘要:
      本文研究了腰椎椎管CT图像的三维重建和动态显示,为脊柱生物力学的研究提供了一种全新的研究手段。应用轮廓重建方式对人体完整腰椎进行三维重建,重建的图形可进行空间任意的旋转、切割和投影变换,实现动态显示,精确地展示出腰椎椎管的三维空间结构和形态。在腰椎三维图形重建的基础上,应用图形处理技术对椎管有效截面积进行运动变化后的测量,获得有效截面积百分比。研究结果证明椎管有效截面积的动态变化与腰椎疾病临床症状和治疗效果有关。腰椎椎管CT图像三维重建的方法可推广到其他领域。
英文摘要:
      This paper report a study of three-dimensional(3D)reconstruction and dynamic display for a series of CT images of lumbar vertebral canal.It provides a newresearch method for the spinal column biomechanics.By means of the contour reconstruction we made 3D reconstruction for complete human lumbar vertebra.The reconstructive graphic could be rotated cut and transformed in any orientation.It could realize dynamic display and accurately show the structure and form of lumbar vertebral canal.Based on the 3D image reconstruction,image processing.technique was used to measure the spinal canal effective area(SCEA)after dynamic exchange and get the result of the percentage of effective area.The result showed the dynamic exchange of SCEA was related to the clinical symptom and the therapeutic effect of the lumbar vertebra disease.This method of spinal Canal CT image 3D reconstruction could extend its use into other fields.
