Patents by Inventor Georg Martschenko

Georg Martschenko 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 and device for monitoring local coils
    Patent number: 11226384
    Abstract: A system and method are provided for operating a magnetic resonance tomograph. A transmitter of the magnetic resonance tomograph transmits a predetermined test pulse with a reduced power. The magnetic resonance tomograph receives the test pulse with the local coil. A controller compares the received test pulse with a predetermined pulse response and emits a warning signal when the received test signal differs from the predetermined pulse response.
    Type: Grant
    Filed: December 10, 2019
    Date of Patent: January 18, 2022
    Assignee: Siemens Healthcare GmbH
    Inventors: Jürgen Nistler, Volker Matschl, Stephan Biber, Rainer Kurth, Christian Wünsch, Georg Martschenko
  • Apparatus and method for B1 limiting
    Patent number: 11073582
    Abstract: A magnetic resonance tomography unit and a method for operating the magnetic resonance tomography unit are provided. The magnetic resonance tomography unit includes a transmitter for generating excitation pulses with a wavelength lambda, an antenna for emitting the excitation pulses, a feed line, and a voltage sensor. The voltage sensor is arranged on the feed line at an effective distance corresponding to a multiple of half the wavelength lambda from a feed point on the antenna.
