摘要

给出一种三维Q值成像方法和计算流程。模型的参数化采用矩形网格形式,计算中对射线路径的求解采用三维有限差分,反演方程的求解利用反投影法。数值模拟表明了方法的可行性,用于实测资料处理,得到了有意义的结果

Abstract

A method and a program chart for 3-D attenuation tomog raphy are developed.Rectangularg rid is used in model parameterization.Back projection tomography is applied to inverse solution.Numerical modeling shows the feasibility of the method, which produces significant results in data processing
