This paper describes a realistic simulator for the Computed Tomography (CT) scan process for motion analysis. In fact, we are currently developing a new framework to find small motion from the CT scan. In order to prove the fidelity of this framework, or potentially any other algorithm, we present in this paper a simulator to simulate the whole CT acquisition process with a priori known parameters. In other words, it is a digital phantom for the motion analysis that can be used to compare the results of any related algorithm with the ground-truth realistic analytical model. Such a simulator can be used by the community to test different algorithms in the biomedical imaging domain. The most important features of this simulator are its different considerations to simulate the best the real acquisition process and its generality.
本文描述了一种用于运动分析的计算机断层扫描（CT）过程的逼真模拟器。事实上，我们目前正在开发一个新框架，以从CT扫描中发现微小运动。为了证明该框架或任何其他潜在算法的逼真度，我们在本文中展示了一个模拟器，用于在已知先验参数的情况下模拟整个CT采集过程。换句话说，它是一个用于运动分析的数字体模，可用于将任何相关算法的结果与真实的逼真分析模型进行比较。这样的模拟器可供该领域的研究人员用于测试生物医学成像领域中的不同算法。该模拟器最重要的特点是其在模拟真实采集过程时的不同考量以及通用性。
