Patent Number Title Of Patent Date Issued
5107216 Nuclear magnetic resonance imaging apparatus April 21, 1992
In an imaging apparatus using the nuclear magnetic resonance, a solenoid coil and a slot-resonator coil are combined with each other so as to constitute a quadrature-phase detection probe. In order to operate the slot-resonator coil at low frequency, inductance is added to the slot-r
4929881 Probe for nuclear magnetic resonance apparatus May 29, 1990
There is provided a probe to detect a nuclear magnetic resonance signal in which each of a plurality of arms forming a current path of an Alderman-Grant type coil is divided into two conductor plates, the two conductor plates are connected by an inductor, and a resonance frequency is
4875013 High-frequency coil for nuclear magnetic imaging October 17, 1989
A high-frequency coil of the type of slot resonator in which outer conductors that have wing portions at both ends thereof and that are divided, are formed on the cylindrical surface, and ring-like inner conductors are formed on the inside of the wing portions. The wing portions have
4875010 Circuit for detecting AC magnetic field due to magnetic resonance with a variable resistance for October 17, 1989
In a signal detecting circuit of, for example, an NMR apparatus, a signal transmission path transmits an AC magnetic flux signal to be superposed on a DC magnetic field whose strength does not change with time during a period of signal detection. The signal transmission path comprises a
4825163 Quadrature probe for nuclear magnetic resonance April 25, 1989
A quadrature probe for nuclear magnetic resonance includes two sets of coils which are combined with an angle of therebetween. Four pieces of outer conductors and two pieces of ring-shaped inner conductors are capacitively coupled to each other through an insulator or an air g
4777443 Inspection apparatus based on nuclear magnetic resonance October 11, 1988
Disclosed in a nuclear magnetic resonance (NMR) based inspection apparatus using an SQUID flux meter for detecting a small NMR signal, in which a receiving coil for receiving the NMR signal from an object is connected to a mixer, which mixes a reference high-frequency signal with the NMR
