为DEC VAX计算机创建了一个模块化的、用户友好的NMR成像计算机模拟。这种模拟是新颖的，复杂的成像现象，如化学位移和流动，可以很容易地研究。其他功能包括自旋扭曲和反投影成像、电影生成、图像对比度模拟、复合脉冲序列、运动伪影、混叠、选择性激励、场不均匀性、噪声和信号平均。该模拟集成了快速傅立叶变换和图形模块，用于处理和显示一维和二维图像。示出了说明程序的功能的例子。该模拟是一个有用的工具，为复杂的和初用户的核磁共振成像。它可以作为研究MRI现象的绘图板和演示基本技术的教学程序。出版社：Academic Press，Inc.
A modular, user‐friendly computer simulation of NMR imaging was created for the DEC VAX computer. This simulation is novel in that complex imaging phenomena, such as chemical shifts and flow, may be easily studied. Other features include spin warp and backprojection imaging, movie generation, and simulation of image contrast, composite pulse sequences, motion artifacts, aliasing, selective excitation, field inhomogeneity, noise and signal averaging. The simulation incorporates fast Fourier transform and graphics modules for processing and display of one‐and two‐dimensional images. Examples which illustrate features of the program are shown. The simulation is a useful tool for both the sophisticated and the beginning user of NMR imaging. It serves as a drawing board for studying MRI phenomena and a teaching program for demonstrating basic techniques. © 1986 Academic Press, Inc.
