Ev. Malikov et al., Spatial resolution and scanning time in the optical tomography of absorbing 'phantoms' under multiple scattering conditions, QUANTUM EL, 30(1), 2000, pp. 78-80
Photon-counting optical tomography was used in the visualisation and projec
tive reconstruction of the image of a strongly absorbing inclusion (a 'phan
tom'), 6 mm in diameter, hidden by multiple scattering processes in a model
object (diameter 140 mm, absorption and scattering coefficients 0.005 and
1.4 mm(-1), respectively). It was demonstrated experimentally that when the
probe radiation power was 10-13 mW the minimal (corresponding to the poore
st signal/noise ratio similar to 1) measurement time (photon-counting time)
was 0.8 s per one measurement point and the total time needed to scan the
whole object was less than 410 s.
