    • The invention relates to an NMR device for detection of resonant protons contained in an object. The device comprises permanent magnets for producing a static and uniform magnetic field in a region located outside the device with respect to which the object will be positioned, these permanent magnets being laid out around an axis on which the said region is located, such that their magnetization direction is directed towards the said region and such that the magnetization values of the permanent magnets combine their effects to produce the static and uniform magnetic field in the said region. The device also comprises means for emission of an electromagnetic signal to the said region and reception of an electromagnetic signal returned from the said region in response to the emitted signal, these means being located inside the space delimited by the said permanent magnets.
    • 本发明涉及用于检测包含在物体中的共振质子的NMR装置。 该装置包括永磁体,用于在位于装置外部的区域中产生静态和均匀的磁场,相对于物体将被定位在该区域周围,这些永磁体围绕所述区域所在的轴布置,使得它们 磁化方向指向所述区域,并且使得永磁体的磁化值结合其效应以在所述区域中产生静态和均匀的磁场。 该装置还包括用于发射到所述区域的电磁信号并响应于所发射的信号接收从所述区域返回的电磁信号的装置,这些装置位于由永磁体限定的空间内。
