Title: Ultrasound-modulated optical tomography
Author: Nam, Haewon
Abstract: Ultrasound -modulated optical tomography is modeled by a linear integral equation and an inverse problem involving a diffusion equation in n spatial dimensions , n=2 , 3 . Based on measured data , the optical absorption coefficient ? is reconstructed inside of a given domain . We make a two -step mathematical model . First , we solve a linear integral equation . Assuming the energy fluence rate has been recovered from the previous equation , the absorption coefficient ? is then reconstructed by solving an inverse problem . Numerical experiments are presented for the case n=2 . Two methods are used for the numerical experiments , gradient descent and levelset . At the end , advantages and disadvantages of those two methods are mentioned .
