Paper Abstract

Finite element method is a general approach for diffuse optical tomography, and the accuracy of which is closely related to the type of elements used. In this paper, we investigate the differences between linear element and quadratic triangular element in the forward problem of diffuse optical tomography. The results show that quadratic element is a better compromise between high accuracy and low time consumption compared to the linear element. This means high order element is a better choice for the diffuse optical tomography.
