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.
