Adam Wax of Duke University describes a method for early cancer detection using coherence imaging in his presentation, "Early Cancer Detection with Coherence Imaging."
The standard surgical biopsy for determining the progress of a disease such as cancer suffers from poor discrimination, a long lead time, and variability in the diagnosis. Wax describes an optical biopsy technique using angle-resolved low-coherence interferometry to measure the size of cells, and compared the method to traditional biopsy results. A significant increase in size appears to be a very specific indicator of disease progress. There is need for increased depth penetration and resolution which may be provided by a combined ultrasound technique.
Adam Wax is an associate professor of Biomedical Engineering at Duke University. His research includes optical spectroscopy for early cancer detection, novel microscopy and interferometry techniques.
