给出了具有多个运行源的椭圆型方程反问题的一种数值方法。该算法不依赖于对解决方案的良好的第一次猜测。文中给出了该方法的“近似全局收敛”性质。在扩散光学层析成像的实际数据上验证了该算法的性能。直接应用于近红外激光成像技术,用于在小动物的大脑中检测中风。
A numerical method for an inverse problem for an elliptic equation with the running source at multiple positions is presented. This algorithm does not rely on a good first guess for the solution. The so-called “approximate global convergence” property of this method is shown here. The performance of the algorithm is verified on real data for Diffusion Optical Tomography. Direct applications are in near-infrared laser imaging technology for stroke detection in brains of small animals.
