Abstract:
In this study, a novel approach for optical imaging of tissue based on diffusely reflected photons was investigated. The examination object was an established solid breast phantom, which contains two absorbing lesions at different depths. The aim was to generate an absorption contrast image using depth discrimination to detect a lesion. The main questions was whether the required depth sensitivity is achievable with a near infrared line light source and a charge-coupled-device-camera. Different light sources were examined by comparative measurements. During the investigations observed speckle-effects could be reduced. The results of this study indicate that a translation of the approach from the breast phantom to in vivo studies appears feasible.
