Abstract: An apparatus for image elastic scattering spectroscopy is disclosed that is comprised of a light source for generating polarized light. Means are provided to convey the polarized light to a target. A collector receives light reflected from the target. A detector is responsive to the collector for generating images at both parallel and perpendicular polarizations for each of a plurality of wavelengths. A range finder detects a distance to the target. Control electronics control the image generation and the range finder. The apparatus may be configured to image areas on the surface of the body or configured so as to be inserted into various body cavities. Typically, the apparatus will be used in conjunction with an analyzer for analyzing the images for evidence of abnormal cells. Methods of gathering data and of screening for abnormal cells are also disclosed.

Abstract: The present disclosure involves a method of preparing a cervical sample for medical examination in which a papanicolaou stained sample is additionally stained with a label targeted to one or more high risk cancer markers to allow for optical detection of the human papilloma virus. That optical detection can be combined with morphometric detection of abnormal cells, which may be improved by multispectral imaging using an acousto-optic tunable filter. Several variations of screening methods and an apparatus for performing the methods are disclosed.
