Images analysed quantitatively for intensity of backscattered light from the epithelia and for rates of signal decay over the depth of epithelia OCT images, which contain information about epithelial and stromal structure, can be clinically obtained. Image features of normal and abnormal cervical epithelium differ significantly.
OCT is a novel technique that can map subsurface tissue structure to a
