Patents by Inventor Gunter Schwierz

Gunter Schwierz 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).

  • Radiation diagnostic device for generating tomographic images
    Patent number: 4455667
    Abstract: In the exemplary embodiments a layer is to be scanned which is generally parallel to the longitudinal axis of the patient support. For example, a radiation source and a radiation receiver may be rotated in an arc about a rotational axis which lies perpendicular to the longitudinal axis of the patient support to scan a layer area in such a way that the scanned layer within the exposure subject is traversed exclusively along beam paths each of which is crossed along its entire length in the subject by a multitude of other beam paths.
    Type: Grant
    Filed: February 20, 1981
    Date of Patent: June 19, 1984
    Assignee: Siemens Aktiengesellschaft
    Inventors: Gunter Schwierz, Rudolf Schittenhelm, Gunter Schmitt, Edgar Tschunt

  • Tomograph for producing transverse layer images
    Patent number: 4176279
    Abstract: In an illustrated embodiment, the fan shaped beam of penetrating radiation has a central ray directed offcenter relative to a row of detectors e.g. by a distance corresponding to one-fourth the detector separation. In this way, for each projection with a given central ray angle, further points can be derived by interpolation using the measurements from other projections. With a given number of detector elements, the number of points per projection can be doubled in this way.
