Reconstructed 3D images using C GPU C code (a) for simulation phantom. The phantom has two inhomogeneities, one cylindrical and the other spherical having 𝜇_𝑎 of 0.03 and 0.02 mm⁻¹, respectively, and (b) experimental phantom with two cylindrical inhomogeneities having diameters of 10 and 12 mm and absorption coefficients of 0.02 and 0.035 mm⁻¹, respectively. The background absorption and scattering coefficients are 0.005 mm⁻¹and 0.8 mm⁻¹. The inhomogeneities run through the length of the phantom.
