Abstract
Surface weighted imaging in a wide-field manner is useful for many biomedical applications such as margin status determination in breast conserving surgery. One technique that has shown promise for this application is modulated imaging at high spatial frequency. A new technique to provide similar information in a more compact manner with the ability to customize based on desired depth penetration was developed. This technique involves quickly scanning a point source over the tissue surface and selective removing diffuse photons in image processing. These two techniques were compared using custom made depth phantoms of tissue equivalent material.
