A hybrid imaging method based on diffuse optical tomography and optomechanical method to detect a tumor in the biological phantom

摘要

In this study, a new combined method to detect abnormality inside the biological phantom is presented. We describe a new approach to breast imaging based on diffuse optical tomography and optomechanical imaging. In this method, the diffusion of photons inside compressed breast phantom is used to detect the location of abnormalities. The variation of optical properties of phantom induced by compression can affect on diffusion of photons. Therefore, these variations of optical properties of phantom must be considered in this imaging method. In current study, the ability of this method to detect the location of tumor inside biological phantom is evaluated. The results show that the accuracy of this method is better than diffuse optical tomography. (C) 2014 Elsevier B.V. All rights reserved.
