摘要: In an apparatus for performing magnetic resonance measurements by means of orthogonal system excitation detection coils there is provided a switching circuit powering and reading the coil which includes 1/4 λ coaxial conductor as connection between two assemblies with 90° phase delay first second assembly device. By suitable tuning relevant components coils, preferably based on 50 Ohms, simple appropriate matching correction thus achieved. Specifically, r.f. power source can be connected to via n conductor. open condition during detection, represents infinite impedance circuit.
