The image of an object hidden in highly scattering media was reconstructed using a fast, noise-resistant algorithm newly applied to diffusion tomography. A pulsed light source producing scattered and transmitted light is examined at multiple times. Multiple source detector pairs around the medium are used to obtain data in many different directions. An inverse scattering algorithm with nonuniform regularization achieves rapid inversion convergence.
利用一种新应用于扩散层析成像的快速、抗噪声算法，重建了隐藏在高散射介质中的物体图像。对产生散射光和透射光的脉冲光源进行多次检测。介质周围的多组源探测器对用于在许多不同方向上获取数据。一种具有非均匀正则化的逆散射算法实现了快速的反演收敛。
