    • The subject invention relates to a method and apparatus for producing stimulated MRI data. In an embodiment, a remote-controlled “smart phantom” can produce simulated data. The simulated data can be acquired from a MRI system. The subject device can generate control signals and send the generated control signals to secondary coils/probes placed in the subject smart phantom. The control signals determine the current flow in the secondary coils/probes, which act as local spin magnetization amplifiers and thus produce regions of variable contrast to noise ratio. The control signals can be generated with various parameters, such as BOLD models, different levels of contrast-to-noise ratio (CNR), signal intensities, and physiological signals. Comparisons can be made with the widely-used simulated data by computers. Validation of the subject smart phantom can be performed with both theoretical analysis and data of human subjects.
    • 本发明涉及一种用于产生模拟MRI数据的方法和装置。 在一个实施例中,远程控制的“智能幻影”可以产生模拟数据。 可以从MRI系统获取模拟数据。 主体装置可以产生控制信号,并将产生的控制信号发送到放置在主体智能幻影中的次级线圈/探头。 控制信号确定次级线圈/探头中的电流,其作为局部自旋磁化放大器,从而产生可变对比度噪声比的区域。 控制信号可以用诸如BOLD模型,不同等级的对比噪声比(CNR),信号强度和生理信号等各种参数产生。 可以用计算机广泛使用的模拟数据进行比较。 可以通过理论分析和人类受试者的数据进行主体智能幻影的验证。
