摘要： 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 a width different from the width of the inner conductors. The self resonance frequency of the coil is adjusted by adjusting the width which is smaller than the other width. Further, the neighboring tips of the wing portions are opposed to each other via an air gap. The self resonance frequency is also adjusted depending upon the position of the dielectric plate inserted in the gap.

摘要： A quadrature probe for nuclear magnetic resonance includes two sets of coils which are combined with an angle of 90.degree. 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 gap. In the outer conductor(s) in at least one of a set of outer conductors disposed at positions symmetrical with respect to each other so as to form a first coil and a set of outer conductors disposed at positions symmetrical with respect to each other so as to form a second coil, a conductor member(s) for adjustment is attached in parallel to the arm portion(s) in that outer conductor(s) of that set. Alternatively, the arm portion(s) itself in that set is slidably attached to the wing portions in that set.

摘要： A bolus of magnetized blood is formed by at least two radio frequency magnetic fields, and readout gradient magnetic fields are repeatedly applied at a proportion of 1:-2:1 along a blood vessel so as to continuously obtain a first echo signal whose phase change due to velocity is corrected, from the moving bolus. This first echo signal provides velocity information on the blood stream. The sequence of the readout gradient magnetic fields is repeatedly applied at a proportion of (.sqroot.2-1):-2:2:-(.sqroot.2-1) so as to continuously obtain a second echo signal whose phase change due to velocity and acceleration is corrected, from the moving bolus. Acceleration information of the blood stream is extracted by calculating the difference between the first echo signal and the second echo signal. The velocity information and/or the acceleration information is displayed in superposition with a specific blood vessel of an angiogram shot in advance.

摘要： In a magnetic resonance imagining method, using an effect that a fluid flows out of a plane where it is selectively excited between the time of applying a 90.degree. radio frequency pulse and the time of applying of a 180.degree. radio frequency pulse, two, images are separately constructed from multiple echo signals which are sampled before applying the 180.degree. radio frequency pulse and multiple echo signals which are sampled after applying the 180.degree. radio frequency pulse. An image of the fluid flow and an image of a static part are separated from each other based on a difference between the two constructed images.

摘要： A method of finding error distribution in the static magnetic field and distribution of deviations from straight lines in the gradient magnetic fields of an NMR imaging apparatus which employs the applied spin-warp method. A phantom whose shape has been known is measured in the read-out gradient magnetic fields having different polarities to obtain two spin density distribution images. The two images are then compared with the shape of said phantom to measure the distortion distributions of the images. Error in the static magnetic field and deviations of the gradient magnetic fields from the straight lines are analyzed from the distortion distributions. From the thus obtained error distribution, furthermore, distortion induced in imaging the object is estimated, and the distortion contained in the image that is reconstructed from the spin density of the object by the spin-warp method is corrected using the thus estimated value.

摘要： 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 signal so that the NMR signal is reduced to a low-frequency signal having a differential component of frequencies of both signals, and the low-frequency signal is applied to the input coil of the SQUID flux meter so that it is converted into a voltage signal. The mixer circuit includes Schottky diodes operative at a liquid helium temperature or Josephson junctions, and the portions of apparatus from the reception coil up to the SQUID flux meter are operated in a superconductive state at a liquid helium temperature.
