摘要

Artificial Joint Reconstruction System based Medical Image is a typical multi-subjects field. It involves medical image process, three-dimensional reconstruction and manufacturing, etc. These kind of machining artificial joints are very helpful for reducing all kinds of syndromes on patients by transpositional operations. At the same time, successful three-dimensional reconstruction technology on medical image is widely used in clinic medical diagnosis and operation layout. So this research is very important in both academic and practical significance. In this paper it is described a CAD graphics system that analyzes CT images slices and reconstruct 3D images of bones for preoperative surgery planning. The purpose of designing this system is to aid an orthopedic surgeon in performing femoral head replacement surgery. The first part of system reads in CT scan data of patient's femur and performs image analysis. To interact with the surgeon's examination, CT images can be edited and manipulated on a high-resolution monitor for observation. The output of this image analysis will be reconstructed into 3D solid bones by the second part of the system. This second part of the system is a 3D graphic training system that can emulate the procedures of femoral head arthroplasty. This planning system provides a surgeon to simulate the bone alignment, cutting, and implant placement before the operation.
