Patents by Inventor Heinz E. Kranberg

Heinz E. Kranberg 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).

  • X-Ray diagnostic installation comprising means for the formation of a transparency signal
    Patent number: 4455669
    Abstract: In an exemplary embodiment, two radiation detectors are arranged behind the radiography subject. One of the detectors is covered by a radiation filter. A different radiation attenuation along the radiation paths of the respective detectors thereby takes place, so that, through division of the output signals of the detectors, a quotient signal can be obtained which corresponds to the radiation transparency of the radiography subject.
    Type: Grant

  • Apparatus for the measurement of the X-ray tube high voltage
    Patent number: 4400821
    Abstract: In an exemplary embodiment, two radiation detectors are present which are covered on their inlet sides for the radiation by two x-ray filters of different absorption. A divider divides the two output signals of the radiation detectors so that its output signal is a measure of the time variation of x-ray tube voltage during an exposure. The output signal of the divider is supplied to a time measurement circuit which provides a measure of the exposure time during which the x-ray tube voltage is greater than or equal to a predetermined value.
