摘要

在这项工作中,我们研究了一个反问题,在确定多重系数在一个耦合扩散系统产生的时域漫射光学层析成像与荧光。我们同时恢复了背景吸收系数,光子扩散系数和荧光吸收在生物组织中的分布随时间的边界测量。建立了该多系数联立反问题的唯一性定理。在此基础上,考虑了含不同形状夹杂物的非光滑吸收的数值反演。

Simultaneous uniqueness and numerical inversion for an inverse problem in a coupled diffusion system
In this work, we investigate an inverse problem in determining multiple coefficients in a coupled diffusion system arising from the time-domain diffuse optical tomography with fluorescence. We simultaneously recover the distribution of the background absorption coefficient, photon diffusion coefficient, and fluorescence absorption in biological tissue by time-dependent boundary measurements. We build the uniqueness theorem for this multiple coefficients simultaneous inverse problem. After that, the numerical inversions for non-smooth absorption featuring various shaped inclusions are considered.
