摘　　要：弹性波CT技术即弹性波层析成像技术,本文采用理论分析与正反演对比相结合的方法,研究了弹性波CT技术的分辨率问题、低速色盲问题和像元划分问题,提出了各种观测系统的最高分辨率估算公式,指出了二侧透视观测系统的重大缺陷、弹性波CT技术的"低速色盲"本质以及划分像元的一般原则。The methods of logic analysis and contrast between forward and inverse are used in the paper. The resolution of computerized tomography technology, low speed color- blind and pixon map division are studied. In addition, the highest resolving power estimate -formulas about several observation systems are provided. Furthermore, he highest resolution estimate-formula about kinds of observation system is proposed, and the serious flaw of two-side perspectives observation systems pointed out and the essence of ＂ low speed colorblindness＂ of elastic wave computerized tomography technology and general principle of pixon map division are described.

关 键 词：弹性波CT 分辨率 可靠性 像元划分 低速色盲
