  • Patent number: 10750947
    Abstract: A system and method for intraoperative fluorescence imaging. A system for intraoperative fluorescence imaging includes a visible light source, a laser light source, a visible light image detector, a fluorescence image detector, radio frequency (RF) circuitry, and an image processing system. The RF circuitry is coupled to the laser light source and the fluorescence image detector. The RF circuitry is configured to modulate laser light generated by the laser source, and modulate an intensifier of the fluorescence image detector. The image processing system is coupled to the visible light image detector and the fluorescence image detector. The image processing system is configured to merge a fluorescence image produced by the fluorescence image detector and a visible light image produced by the visible light image detector to generate an intraoperative image showing an outline of a region of interest identified in the fluorescence image overlaid on the visible light image.

  • Publication number: 20160029948
    Abstract: Methods and imaging agents are used to functionally image lymph structures and to identify, diagnose, assess, monitor and direct therapies for lymphatic disorders. Embodiments of the methods utilize highly sensitive optical imaging and fluorescent spectroscopy techniques capable of rapid temporal resolution to non-invasively track or monitor packets of imaging agents flowing in one or more lymphatic structures in human patients to provide quantitative information regarding lymph propulsion and functionality of the lymphatic structures. An imaging agent comprises a fluorophore labeled peptide capable of binding integrin ?9?1 on a lymphatic structure.

  • Patent number: 8989847
    Abstract: Novel methods and imaging agents for functional imaging of lymph structures are disclosed herein. Embodiments of the methods utilize highly sensitive optical imaging and fluorescent spectroscopy techniques to track or monitor packets of organic dye flowing in one or more lymphatic structures. The packets of organic dye may be tracked to provide quantitative information regarding lymph propulsion and function. In particular, lymph flow velocity and pulse frequency may be determined using the disclosed methods.

  • Patent number: 6595277
    Abstract: A water well filter device and a method for preventing airborne microorganisms from entering into a water well are disclosed. The water well filter device of the present invention contains a microorganism filter element having sufficiently small pore sizes to stop microorganisms from passing through. The water well filter device can further contain a pre-filter, a vacuum relief valve, or both. The method for preventing airborne microorganisms from entering into a water well involves connecting the water well filter device of the present invention to an opening of the well that is otherwise sealed from open air.
