Abstract
A transmission/reception arrangement for a diagnostic magnetic resonance apparatus has an antenna, a matching and tuning circuit and a signal transmission line. The antenna together with the matching and tuning circuit is fashioned for exciting and/or receiving proton magnetic resonance signals having a first frequency. A reactance circuit is connected between the matching and tuning circuit and the signal transmission line. The reactance circuit is fashioned such that a reflection factor to the second transmission line substantially disappears at a second frequency. The apparatus is thus provided with the capability of conducting examinations using hyperpolarized gases, while still preserving the capability of conducting imaging with conventional proton (.sup.1 H) signals without modification.
