Optical CT using the temporally extrapolated absorbance method (TEAM)

In this paper, we describe the experimental evaluation of the temporally extrapolated absorbance method (TEAM) in turbid media. The TEAM is the method utilizing the extrapolated absorbance, obtained by temporally extrapolating the time-resolved absorbance difference between an object and a reference to the shortest photon flight time. Using the TEAM, we reconstructed the CT image of an absorber-containing cylinder in a strong scattering media and compared it with those obtained with the time gating and cw methods based on the same data. Among the three methods, the TEAM presented best spatial resolution in the reconstructed CT images.
