全髋关节置换术（THA）中滑动面脱位、松动或磨损等并发症是严重的临床问题，患者的日常活动受到一定程度的限制。然而，很难识别运动过程中部件的情况并预测并发症。我们开发了 4 维人体模型，可以可视化患者骨骼的运动，并使用计算机模拟来估计并发症的风险。首先，我们根据 CT 数据构建了患者下肢的 3 维骨骼模型。然后，我们从红外位置传感器（VICON512，VICON Motion Systems，英国）获取运动捕捉数据，并驱动与捕捉到的数据相对应的患者骨骼模型。因此，我们能够预测安装人工髋关节后的预后，并且在使用开放式 MRI 进行实验后，我们检查了该系统中测量的准确性。
In total hip arthroplasty (THA), complications such as dislocation, loosening, or wearing of the sliding surface are serious clinical problem, and the daily motion of patients has been limited to some extent. However, it is hard to recognize the situation of the components during movement and to predict complications. We have developed the 4-dimensional human model that can visualize the motion of the patient's skeleton and estimate the risk of complications using computer simulation. At first we constructed a 3-dimensional skeletal model of the patient's lower limb from CT data. Then we acquired motion capture data from an infrared position sensor (VICON512, VICON Motion Systems, UK), and drove the patient's skeletal model corresponding to the captured data. Thus we were able to predict the prognosis after the installation of the artificial hip joint, and we have examined the accuracy of the measurements in this system following an experiment using an open MRI.
