A fast image reconstruction algorithm for continuous wave diffuse optical tomography

Abstract

In this paper, we propose a fast high resolution image reconstruction algorithm for continuous wave (CW) diffuse optical tomography (DOT). First, we devise the overlapped-truncated-Jacobi singular value decomposition (OSVD) scheme for the image reconstruction. Second, we adopt the cubic interpolation to enhance the image quality. Simulation results show that our proposed algorithm effectively reduces the computing complexity, keeps the confidence of the image and enhances the image resolution.
