Improved Image Reconstruction Using Multi frequency Data for Diffuse Optical Tomography

Our goal is to investigate the possible merits of utilizing multi frequency boundary data to obtain better images through Diffuse Optical Tomography or DOT. The driving force behind this pursuit is finding a lternatives t o conventional measurement procedures that yield information rich data but are expensive and time consuming. This method of imaging could also help in addressing the ill posedness inherent in image reconstruction. Keeping these goals in mind, boundary data for 5 different modulation frequencies have been generated, cascaded together and used to reconstruct images. Subsequent evaluation of the reconstructed images have been carried out. The results we obtained have led us to the conclusion that utilizing multi frequency data would indeed provide an economically feasible solution for enhancing the quality of the reconstructed images.
