April 29, 2019. Estimated Expiration Date is calculated based on simple USPTO term provisions. It does not account for terminal disclaimers, term adjustments, failure to pay maintenance fees, or other factors which might affect the term of a patent.Patent ReferencesMethod of detecting anomalies of the skin, more particularly melanomae, and apparatus for carrying out the method System and method for localization of malignant tissue Tunable excitation and/or tunable emission fluorescence imaging Fluorescence imaging system Method and apparatus for imaging and sampling diseased tissue using autofluorescence Method and apparatus for reflected imaging analysis Optical imaging methods Patent #: 6161031 InventorsAssigneeApplicationNo. 301546 filed on 04/29/1999US Classes:600/160, Having imaging and illumination means600/477With comparison means (e.g., ratio of or comparison to a standard)ExaminersPrimary: Leubecker, John P.Attorney, Agent or FirmInternational ClassesA61B 001/04A61B 006/00 Foreign Application Priority Data1998-05-01 JPAbstractData of ordinary color observation image obtained by picking up an object according to a RGB flame sequential system and data of fluorescent observation image obtained when the object is irradiated with excitation light are respectively transmitted to the PC. The PC calculates luminance values based on the data of ordinary color observation image to extract an area where luminance is higher than a first threshold, and extracts areas where luminance is lower than second threshold which is higher than the first threshold from the data of fluorescent observation image. The PC specifies an area which is included in both of these extracted areas, as an area having a high possibility of indicating an abnormal area.Field of SearchWith camera or solid state imagerHaving imaging and illumination means Light source Visible light radiation With comparison means (e.g., ratio of or comparison to a standard) Light conducting fiber inserted into a body Detecting nuclear, electromagnetic, or ultrasonic radiation LUMINOPHOR IRRADIATION | |
