摘要
鉴于目前市场上的医用CT基本上都采用第三代CT原理。本文在比较理想CT系统与实际系统差异的基础上,分析了第三代CT图像常见伪影、产生因素和矫正技术。以达到有效帮助CT理论研究工作者、医务工作者和维修工程师加深对CT图像伪影的理解和正确快速采取措施矫正或减少图像伪影的目的。
Based on the fact that currently hospitals CT devices are almost the 3rd generation CT principle, comparing the difference of real CT device and ideal one, this paper analyzes the common artifacts existing in the 3rd CT, its reason and how to correct them. This will help the CT researcher, doctors and serve engineers to deepen the comprehension for CT artifacts, and help them to do the trouble shooting work more effectively.
