Abstract

Diffuse Optical Tomography (DOT) is a typical inverse problem that aims to retrieve internal chromophore distributions non-invasively. Algebraic Reconstructions techniques (ART) are one of the popular image reconstruction techniques used in DOT. We investigate in this report the influence of the order in which data are accessed in ART. Simulations mimicking breast tissues in transmission geometry with contrast agent tumor enhancement were used to evaluate the image quality of the diverse projection access investigated. We show that by selecting proper projection access order, the convergence speed can be significantly improved when ART is used to perform DOT. Moreover, low-contrast detection is improved.
