Imaging of inhomogeneities in a turbid medium with transmitted optical signal represents a crucial technique for optical diagnosis of abnormal cells in human tissues, particularly important for early detection of female breast cancer. In this paper, we present the results of our simulation and experimental studies. In the simulation study, we propose a new technique using transient diffuse photon density waves for imaging reconstruction. In the experimental study, we demonstrate the assistance of ultrasounds to optical imaging through a turbid medium. For the imaging, we basically utilize transmitted ballistic and snake photons.
