摘要

本文概述了高分辨率计算机断层扫描系统最重要的成像特性。描述了空间分辨率和对比度分辨率(平面内和平面间)，并指出了这两个特性之间的权衡。此外，还显示了非常小的结构可以成像，但不是真实的Hounsfield单元。最后，将噪声设置为与对比度分辨率的关系。

[Imaging properties of a high-resolution CT system].

This paper provides an overview of the most important imaging properties of a high-resolution computed tomography system. Spatial and contrast resolution (inplane as well as crossplane) are described, while the trade-off between those two characteristics is pointed out. Furthermore, it is shown that extremely small structures are imaged, but not with realistic Hounsfield units. Finally, the noise is set into relation to the contrast resolution.
