摘要： A quadrature detection device for magnetic resonance imaging includes a pair of probes each having a pair of first conductors with a vertical arm and wings formed at both ends of the vertical arm and guard rings disposed inside the wings to oppose them and predetermined capacitors. In each probe, the resonance characteristics of the probe has two peaks. Symmetry of the peak existing in the resonance frequency range is effected by spacing the peak existing in a frequency range other than the resonance frequency range apart from the former. Thus, uniformity of the resulting image can be improved. The drop of the Q value of the probe is prevented by shifting the former peak to a higher frequency range than the latter peak. Also, electric symmetry of the probe is maintained.

摘要： Disclosed is an ion trap mass spectrometer improved to obtain a high sensitivity without the lowering of resolution. By fitting a mesh electrode to an aperture (an ion sampling aperture or an ion extracting aperture) made in endcap electrodes constituting an ion trap mass analysis region, a radio frequency electric field in the mass analysis region is not disturbed even if the diameter of the aperture is set to a large value to heighten ion transmission efficiency. By fitting a shield electrode for preventing collision of ions with an insulated ring constituting an outer wall of the mass analysis region, charging up of the insulated ring is prevented to improve stability of detection signals. Furthermore, by arranging a shield member for shielding stray charged particles detouring through the circumference of the mass analysis region to approach an ion detector, generation of noises based on these stray charged particles is prevented.

摘要： This invention relates to a selection method of a specific region of a sample which is suitable for use in a nuclear magnetic resonance (NMR) imaging. Selection of a specific region suitable for obtaining multi-dimensional spatial information can be preferably made. To satisfy this requirement, the spin of the specific region of the sample is brought down in a direction at right angles to a static magnetic field, the regions other than the specific region are, in the mean time, brought down in a direction at right angles to the static magnetic field, and thereafter the static magnetic field is rendered non-uniform to that the spins of the regions other than the specific region become saturated.
