摘要： In a radiation detector, scintillation material flouoresces and the produced light is converted to electrical energy in an adjacent converter, separators are provided in spaces between the adjacent scintillators and converters. The separators may have a greater length than the adjacent scintillators, so that they will extend beyond to reduce cross-talk. The separators can extend toward the source of radiation for a height substantially greater than, and particularly five times, the height of the spaces between the adjacent scintillators to prevent X-ray scattering and function as a collimator. Optically opaque adhesive may be provided on the opposite ends of separators and pairs of scintillators and collimators, to prevent cross-talk.

摘要： In a radiation detector having a scintillator and a photodiode in combination, an amorphous silicon diode of a refractive index of 3.5 or below is used for a photodector to have a decreased junction capacitance. This shifts the spectral sensitivity characteristic of the photodetector toward the short wavelength side, thus providing a low-noise, high-sensitivity radiation detector matched well with the emission spectrum of the scintillator.

Between rungs of a partially cylindrical RF coil, which coil corresponds to a cylindrical RF coil of which part is removed, there are disposed half-loops generating magnetic fields, which are synthesized with magnetic fields generated by loops constituted by adjacent rungs of the partially cylindrical RF coil and rings connecting the rungs to generate a circularly polarized or elliptically polarized magnetic field. Further, high-frequency signals of the same reference frequency having a desired amplitude ratio and phase difference are supplied to the partially cylindrical RF coils and half-loops.

摘要： When multiple types of imaging are performed while moving a table on which a subject to be examined is placed, an imaging efficiency is improved and a high-quality image is obtained within a short time. Therefore, within a predetermined time interval such as an identical period of a periodic living body motion, a predetermined number of echo signals from each of the multiple types of imaging sequences are acquired and the table on which the subject to be examined is placed is moved. Along with the movement of the table, data items within the same range in the Ky-direction as to each of the imaging sequences are acquired, the moving speed of the table is controlled in such a manner that the acquired data items become continuous in the x-direction, and images are reconstructed based on the data items obtained respectively from the imaging sequences.
