本文首先对弹性波CT基本原理进行简要介绍 ,然后对弹性波CT关键技术进行较为详细的分析说明。提出椭圆约束方法实现更快速射线追踪 ,同时指出应用数据校正和误差控制等方法技术 ,能够有效提高解的唯一性和成像精度。最后通过应用实例对所述方法技术的正确性和实用性进行了充分验证。

The fundamental principle of the CT based on the theory of elastic wave ray is briefly introduced, and the key technique of the elastic wave CT is deeply analyzed. It is pointed out that the quick ray trace can be realized by using the method of ellipse restriction, and that the uniqueness of interpretation and the precision of images can be improved by using the data rectification and error controlling technique. Finally the correctness and the practicability of the said method are validated by practical examples.
