Prospects on Time-Domain Diffuse Optical Tomography Based on Time-Correlated Single Photon Counting for Small Animal Imaging

(a) Top view of phantom used in experiments for obtaining speed maps. Inclusions labeled A, B, D, and E of different sizes and at different locations can be inserted in the medium for obtaining regions with scattering coefficient differing from that of the otherwise homogeneous background. In the results given in (b) and (c), the background’s reduced scattering coefficient has value  cm⁻¹. (b) Speed map obtained with inclusion A2 having  cm⁻¹ and A3 with  cm⁻¹. (c) Speed map with inclusions B1, B2, and E6 having, respectively,  cm⁻¹, 2.5 cm⁻¹, and 2.5 cm⁻¹.
