Walter Heinrich Kullmann 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).

  • Method of reconstructing the spatial current distribution in a biological object, and device for performing the method
    Patent number: 5885215
    Abstract: A method of reconstructing the spatial current distribution in a biological object, at least one component of the magnetic field produced by the current sources being measured at a number of points outside the object, after which the current distribution at the volume elements situated within the object is reconstructed from the measuring values. In order to improve the accuracy of reconstruction, in a representation containing the morphological structure of the object the surfaces are specified on which the current sources are presumably present, the reconstruction being limited to the volume elements which are situated on these surfaces.
    Type: Grant
    Filed: June 25, 1990
    Date of Patent: March 23, 1999
    Assignee: U.S. Philips Corporation
