Led induced fluorescence detection system of epithelial tissue

Abstract

A device for irradiating epithelial tissue with a light source between 410 nm and 420 nm and observing the presence of resultant fluorescence induced in the tissue. The device may include a long pass filter blocking light reflected from the tissue surface of 500 nm or shorter. A method for detecting epithelial neoplasia by irradiating tissue with a light source between 410 nm and 420 nm and observing the presence resultant fluorescence induced in the tissue. The method may include blocking reflected light having a wavelength of approximately 500 nm or shorter. The device may be a handheld device containing a light emission source and viewport with long pass filter. The light emission source can be positioned substantially normal to the tissue surface. The device may include a camera and a separately located display and recording capability. The light emission source can be positioned on a handle or upon the periphery of a viewport.
