将三维逆散射方法修改为适合圆柱表面材料的超声波测量形式。该方法应用于三维缺陷断面图像的重建。在此过程中，引入高斯光束轮廓来模拟超声换能器辐射的入射波场。通过对球形和圆柱形腔体的横截面切片进行成像来研究改进方法的性能。
Three-dimensional inverse scattering methods are modified to a suitable form of ultrasonic measurements for the material with cylindrical surface. The methods are applied to the reconstruction of cross-sectional image of three-dimensional flaws. In this process, Gaussian beam profiles are introduced to model the incident wave fields radiated from ultrasonic transducers. The performance of the modified methods is investigated by imaging the cross-sectional slices for the spherical and cylindrical cavities.
