我们引入了一种改进的 Tikhonov 正则化方法，将三维 X 射线乳房 X 线摄影作为扩散光学断层扫描重建的先验。通过模拟，我们表明，通过实施这种 X 射线引导的空间约束，光学图像重建分辨率和对比度得到了提高。我们建议一种寻找最佳正则化参数的方法。所呈现的初步临床结果表明了该方法的实用性。 (C) 2003 年美国光学学会。
We introduce a modified Tikhonov regularization method to include three-dimensional x-ray mammography as a prior in the diffuse optical tomography reconstruction. With simulations we show that the optical image reconstruction resolution and contrast are improved by implementing this x-ray-guided spatial constraint. We suggest an approach to find the optimal regularization parameters. The presented preliminary clinical result indicates the utility of the method. (C) 2003 Optical Society of America.
