本文描述了包括一个新型正面模拟结构的适应电流x线断层术系统的研制。作者利用可编程序的电压源向被研究物体注入电流,由此避免了获得高质量电流源的难度。通过倒置进入许可矩阵,该系统可由计算电压模式获得所需电流驱动模式。x This article describes the development of an adaptive current tomography system that includes a new frontal simulation structure. The author uses a programmable voltage source to inject current into the object under investigation, thereby avoiding the difficulty of obtaining a high quality current source. By inverting into the permissive matrix, the system can obtain the required current drive mode by computing the voltage mode. x
