Diffuse Optical Tomography is non invasive, non ionizing functional imaging modality used for detection of brain tumor and breast cancer. A forward model design depicts the placement of laser source and photo-detector around the tissue boundary. The light propagation on the phantom takes place in Near-Infra-Red wavelength. The incident light on the tissue boundary was absorbed and scattered. The scattered rays are detected by the photo-detector and scattered voltage of the tissue was measured.…
