RECEIVING AERIAL FOR NMR IMAGING APPARATUS

摘要

The quality of the signal received is improved by making the aerial symmetrical. To this effect, the aerial has two branches (18-19) symmetrical in relation to the same plane (XOZ). These branches are connected by their ends to aerial tuning capacitors (C1-C2). The received signal is tapped (41) by a high frequency line (T) incorporated in one of the branches at the connection of one tuning capacitor (C1). The other end (31) of this high-frequency line arranged on the plane of symmetry is connected to an amplifying/impedance transforming circuit (25) of high input impedance.
