计算机辅助种植义耳手术规划的研究

Computer-aided Surgery Planning for Implantation of Artificial Ear

在传统技术中,从事种植义耳修复的临床医生主要通过观察常规X线平片或CT片以及通过经验来规划手术方案。这种术前分析方法对医生的要求很高,分析过程不直观,而且手术风险性高。针对这一现象,本文基于CT成像以及三维重建技术实现了一个计算机辅助的种植义耳修复手术计划系统。该系统有效地克服了传统技术存在的主要缺陷,使得手术规划的准确性、安全性、直观性等方面得到了有效提高。

In conventional ear implantation surgery, clinical physicians usually make a surgery planning based on their observation on series of 2D X-ray images or CT images. Such a planning method requires the physicians to have a high level of clinical experience. Besides, the whole operation is unintuitive, and might have certain risk. Considering these facts, we have developed a computer-aided system for the surgery planning of the implantation of artificial ear based on CT imaging and 3D reconstruction techniques. The system effectively overcomes the main drawbacks in conventional surgery planning techniques, and it makes the surgery planning procedure more precise, safe, and intuitive.
