Patent ID: 8320650

Claim:
A method, comprising: illuminating target tissue with ultraviolet (UV) light having a wavelength of less than 400 nm to produce fluorescense; providing imaging optics capable of producing microscopic resolution within a range from about 0.2 μm to about 5 μm, wherein a portion of said flourescense is directed toward said imaging optics to produce directed flourescense; optically collecting, with said imaging optics, substantially all of said directed fluorescense to produce collected fluorescense; and producing an image from said collected fluorescense; wherein said image comprises an image spatial resolution, wherein said target tissue is within a living organism, wherein the step of optically collecting substantially all of said directed fluorescense is accomplished within a time duration that is no greater than the time it takes said target tissue to move, with respect to said imaging optics, the distance of said image spatial resolution.
