Patents by Inventor Giorgio Margaritondo

Giorgio Margaritondo has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9402593
    Abstract: Images of blood vessels of a body are obtained by injecting a refraction enhancement contrast agent into the blood vessels to increase a difference in refractive indices of the blood vessels and surrounding material. The blood vessels are irradiated with a penetrating radiation, and an image of the blood vessels is generated based on detected radiation. The image has visible edge enhancement features indicating boundaries of the blood vessels.
    Type: Grant

  • Patent number: 6526121
    Abstract: A new radiography method which utilizes contrast enhancement mechanisms with highly collimated X-ray beams without optics to achieve high imaging resolution and improve the time resolution is disclosed. This invention includes irradiating the object with an unmonochromatized beam, specifically highly collimated synchrotron radiation, and detecting an unmonochromatized beam image after the unmonochromatized beam has passed through the object. With compact design, a system for imaging an object with very high resolution, X-ray radiography with a wide range of X-ray sources, such as synchrotron radiation, without any sophisticated X-ray optics is also disclosed. This invention may achieve real-time images with micrometer resolution.
