It has been demonstrated that a relatively low-cost resistive NMR imager can be installed in a normal hospital environment without many major or expensive modifications. The magnet can be adjusted to give adequate uniformity and there is sufficient RF shielding to give good quality clinical images (Fig. 3). The fringe field of the magnet of this system, which operates at the lowest field strength of any commercial NMR imager, does not present a problem to imaging unit staff (NRPB, 1984). The long term reliability and detailed specifications with regard to image quality have yet to be determined. These will be determined whilst the imager is being used for clinical studies as part of the national clinical evaluation of NMR imaging supported by the Medical Research Council.
已经证明，一种成本相对较低的电阻式核磁共振成像仪可以安装在普通医院环境中，无需进行许多重大或昂贵的改造。磁体可以进行调整以提供足够的均匀性，并且有足够的射频屏蔽以获得高质量的临床图像（图3）。该系统磁体的边缘场在所有商用核磁共振成像仪中场强最低，对成像单元的工作人员来说不存在问题（国家辐射防护委员会，1984年）。关于图像质量的长期可靠性和详细规格还有待确定。在该成像仪作为医学研究理事会支持的核磁共振成像国家临床评估的一部分用于临床研究时，将确定这些内容。
