Abstract:

On the basis of the establishment and analysis of the bioluminescence tomography (BLT) system equation, a new equivalent method for multi-spectral optical coefficients is proposed, which convertes the multi-spectral BLT problem into the equivalent mixed-spectral version, thus reducing the dimension and overhead of the system equation. Results demonstrate that this new source weighted method (SWM) is much more accurate and robust than the available arithmetic average method (AAM), keeping the relative error of less than 5％.
