Orthopedic Surgical Planning System Based on Medical 3-D Image Processing

在这个项目中。我们开发了一个基于计算机断层成像系统获得的断层图像序列的骨科手术模拟系统。我们在已开发的颅面部手术模拟系统的基础上，开发了骨科手术模拟的新功能，从而构建了这个系统。开发了以下功能。[前处理]开发了一种自动分离骨盆骨和Femor的功能。[显示功能]采用颅面手术仿真中的图像生成功能作为基本显示功能。我们增加了半透明显示功能来可视化骨盆窝和Femor的关节部分。[操作功能]开发了一种不受干扰的骨骼运动功能。[评估功能]开发了骨盆窝与Femor接触区域的显示功能，以评估它们在手术模拟中的适合性。此外，还开发了其他一些高级功能，以改善系统的人机界面。

In this project. we developed an orthopedic surgical simulation system based on a sequence of sliced imaged obtained by computer tomography imaging system. We constructed this system by developing new functions for orthopedic surgical simulation based on fundamental functions in a cranio-facial surgical simulation system we have already developed. The following functions are developed. [Preprocessing] An automatic disarticulation function is developed to separate pelvis bone and femor. [Display Function] Image generation function in craniofacial surgical simulation is employed as the fundamental display function. We added a translucent display function to visualize joint part of pelvis socket and femor. [Manipulation function] A function of bone movement without interference is developed. [Evaluation function] A function to display contact region between pelvis socket and femor is developed to evaluate fitness of them in surgical simulation.Some other advanced functions are also developed to improve human interface of the system.
