In recent years, the imaging system using Near-infrared Photodynamic Diagnosis (NIR-PDD) has been introduced during surgery. However, these fluorescence images become blurred images by light diffusion or scattering as tumor location is deep tissue. For this reason, the exact lesion location and size are lost. Therefore, several reconstruction techniques using these images are studies. Additionary, these techniques have several problems during surgery because of enormous computational cost. The purpose of this study is to develop real time identification technique using weighted residual method (WRM) and optimization method. In analysis of fluorescence light propagation using WRM, the effects of trial function on computational time and identification accuracy are quite high. The purpose of this study is to discuss about accuracy of trial function by using this identification technique. In this result,a fluorescent source was able to be identified for less than 0.3 seconds and high accuracy by using Lorentz type trial function.
