本文介绍了一种方法来计算和可视化的邻近的软骨下骨表面在动态运动。该方法结合了高速双平面射线照相图像数据和来自计算机断层扫描的三维（313）骨表面信息，以确定动态活动期间的软骨下骨运动。体内软骨下骨运动的知识可能有助于骨关节炎的研究，生物力学建模，并在确定正常和病理关节力学。该方法可用于识别动态运动时的紧密接触区域，计算紧密接触的软骨下骨表面积，确定动态运动时紧密接触面积的变化位置。这些信息都不能使用其他当前可用的3D运动分析技术来获得。示例应用程序显示在犬步态和人类单腿跳跃过程中的动态体内胫骨-股骨骨表面运动。(C)2003爱思唯尔科技有限公司版权所有。
This paper describes a method to calculate and visualize the proximity of subchondral bone surfaces during dynamic movement. This method combines high-speed biplane radiographic image data and three-dimensional (313) bone surface information derived from computed tomography to determine subchondral bone motion during dynamic activities. Knowledge of in vivo subchondral bone motion may be useful in the study of osteoarthritis, in biomechanical modeling, and in identifying normal and pathological joint mechanics. This method can be used to identify the regions of close contact during dynamic motion, to calculate the surface area of subchondral bone within close contact, and to determine the changing position of the close contact area during dynamic activities. None of this informations can be obtained using other currently available 3D motion analysis techniques. Example applications showing dynamic in vivo tibio-femoral bone surface motion during canine gait and human one-legged hopping are presented. (C) 2003 Elsevier Science Ltd. All rights reserved.
