摘要
本文试图从工业CT系统基本原理入手,分析系统结构和基本假设偏离之处,讨论这些偏离对于CT系统性能指标之影响。
Start with and based on the elementary knowledge of computed tomography, analyzing divergence between the system structure and basic presumption, the influence of divergence on the performance parameters of computed tomography system is discussed.
