Patents by Inventor Ruediger Lawaczeck

Ruediger Lawaczeck 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: 9414797
    Abstract: A mammography CT system is disclosed which includes an X-ray generator; and a first radiator-detector system. A contrast medium, including an opacifying element including an absorption peak in a first energy range, is useable for tomographic imaging of a female breast of a patient. After filtering, the X-rays with a prespecified tube voltage that form at an anode, are configured to emit an X-ray spectrum having a second energy range, wherein the radiator-detector system is configured to acquire a plurality of circumferential projections around the breast. The first energy range is a part of the second energy range and the second energy range includes an upper limit of less than 70 keV and a lower limit of greater than 20 keV. A corresponding method for generating tomographic mammography CT images is also disclosed.

  • Patent number: 7672431
    Abstract: To increase the contrast in the imaging in an object under examination that contains at least one radiopaque element, an arrangement that has the following features is used: a) at least one essentially polychromatic x-ray radiation source that emits x-ray radiation, b) at least one energy-dispersive detector, with which the intensity of the x-ray radiation that gets through the object under examination is detectable, c) at least one correlation unit, with which the intensity of the detected x-ray radiation from a pixel of the object under examination with a first energy E1 can be correlated with the intensity of the detected x-ray radiation from the same pixel with a second energy E2, d) at least one output unit for visualizing the object under examination from the pixel signals that are obtained by correlation of the intensities.

  • Publication number: 20070025514
    Abstract: For high-contrast visualization of small lesions or other target areas in tissue that contains at least one opacifying chemical element in the human body, an x-ray arrangement is described that comprises at least one x-ray radiation source that emits essentially polychromatic x-ray radiation, a first detector or several first detectors, with which values of a first intensity of the x-ray radiation that is transmitted through the object under examination can be determined, a second detector or several second detectors, with which values a second intensity of the x-ray radiation that is emitted from the object under examination can be determined, at least one correlation unit, with which the first intensity values of the transmitted x-ray radiation can be correlated with one another with the second intensity values of the emitted x-ray radiation, pixel for pixel, and at least one output unit for visualizing the object under examination from the pixel signals that can be obtained by correlation of the first inte

  • Publication number: 20060257322
    Abstract: The invention relates to pharmaceutical agents that contain at least one fluoroalkyl-containing metal complex that has a critical micelle-formation concentration of <10?3 mol/l and a hydrodynamic micelle diameter (2Rh) of >1 nm, and at least one natural or synthetic epothilone or epothilone derivative, optionally with the additives that are commonly used in galenicals.
