提出了一个可扩展的面向对象的MRI仿真系统。该模拟器使用基于Bloch方程的第一性原理建模来实现核磁共振信号产生的离散事件模拟。结合噪声和部分体积效应的图像生成过程模型也基于第一性原理被开发出来。这用于基于标记数据集生成真实的模拟MRI体积，用于评估分类算法和其他后处理程序。
An extensible object-oriented MRI simulation system is presented. This simulator uses first-principle modelling based on the Bloch equations to implement a discrete-event simulation of NMR signal production. A model of the image production process, incorporating noise and partial volume effects, has also been developed based on first-principles. This is used to generate realistic simulated MRI volumes, based on a labelled data set, for the evaluation of classification algorithms and other post-processing routines.
