Three dimensional image reconstruction in highly scattering turbid media

A novel inverse algorithm, which combines a 2D matrix inversion with a 1D Fourier transform inversion, is designed for obtaining an image of 3D hidden objects in scattering media. The existence of 2D boundaries, on which source-detector pairs are located around, violates the condition for using a 3D Fourier transform inverse imaging. This effect has been handled in our approach. This method greatly reduces the computational burden, compared to standard 3D matrix inversion methods. The result of image of hidden objects using time-resolved simulated data is presented.
