本文提出一种广义绕射层析成像算法,原则上该方法可以适于处理不规则空间数据。该数据弯线排列采集,并采用非均匀背景模型。通过与医学绕射层析成像进行直接对比可见,广义法同样也包括两个处理步骤,即数据滤波器和反向传播。滤波器考虑了模型空间的不规则采样及不均匀的能量覆盖,同 In this paper, a generalized diffraction tomography algorithm is proposed. In principle, this method can be adapted to deal with irregular spatial data. The data is arranged in a series of curves and adopts a non-uniform background model. By direct comparison with medical diffraction tomography, the generalized method also includes two processing steps, namely, data filter and back propagation. The filter takes into account the irregular sampling of the model space and the uneven energy coverage
