Abstract

We have developed a model-based iterative image reconstruction scheme based on the equation of radiative transfer in the frequency domain for the applications in small animal optical tomographic imaging. To test the utility of such a code in small animal imaging we have furthermore developed a numerical phantom of a mouse. In simulation studies using this and other phantoms, we found that to make truly use of phase information in the reconstruction process modulation frequencies well above 100 MHz are necessary. Only at these higher frequencies the phase shifts introduced by the lesions of interest are large enough to be measured. For smaller frequencies no substantial improvements over steady-state systems are achieved in small geometries typical for small animal imaging.
