Patents by Inventor Jeremiah Heilmann

Jeremiah Heilmann 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).

  • Magnetic resonance apparatus with RF amplifier(s) disposed within the spaced distance between the primary and secondary gradient coil windings
    Patent number: 7622927
    Abstract: An arrangement configured for controlling an antenna arrangement in a magnetic resonance device has an antenna arrangement that surrounds an examination region and that has at least one antenna element configured for emitting an amplified transmit signal. At least one amplifier is provided, at the input of which a high-frequency transmit signal is connected, which is present on the output side of the amplifier as an amplified transmit signal. The amplifier is connected to a feed point of the antenna arrangement on the output side, in order to emit the amplified transmit signal. Coil windings of a primary gradient coil are also provided, which at least partially include the antenna arrangement and the examination region. Coil windings of a secondary gradient coil at least partially include the coil windings of the primary gradient coil, the antenna arrangement (and the examination region).
