  • Electronic load simulator device for testing RF coils
    Patent number: 8633706
    Abstract: A magnetic resonance coil testing arrangement includes an electric circuit for emulating an electrical load to a magnetic resonance coil. The electric circuit is configured to emulate an electrical load corresponding to an electrical load induced by organic tissue at the magnetic resonance frequency of the magnetic resonance coil.
    Type: Grant

  • Detuning of an RF shielded MRI scan room
    Patent number: 7548063
    Abstract: The present invention relates to a system and method magnetic resonance (MR) imaging. Furthermore the invention relates to the use of a material and to a computer program. In order to provide a technique which allows to prevent standing waves in an RF cage (3) of a MR imaging system (1) in a very cheap and simple way a MR imaging system (1) is suggested, which comprises a MR imaging apparatus (2) comprising an open magnet system (7), wherein operation of the MR imaging apparatus (2) creates a magnetic resonance field having a MR frequency, and which further comprises an RF cage (3), configured to enclose the MR imaging apparatus (2), wherein the walls (6) of the RF cage (3) are at least partly provided with a covering (5, 10), said covering (5, 10) is adapted in a way that the wavelength of the MR frequency within the covering (5, 10) is reduced.
