摘要
CT能谱成像作为一种全新的成像模式,不但成为业内研究的热点,而且已广泛用于全身各系统病变的诊断,其在降低CT辐射剂量方面的价值也得到了一定的认可。本文就CT能谱成像设备组成、成像原理、图像特点和在降低辐射剂量方面的价值及新进展进行初步的总结、介绍。
CT spectral imaging is a new imaging modality,which has not only become the focus in imaging research,but also has been widely used in the diagnosis of variable diseases. At the same time,the efforts of reducing radiation dose in CT imaging has widely been made. In this paper,we try to make a preliminary summary and introduction to the composition of CT energy spectrum imaging equipment,imaging principles,imaging characteristics,the reduction of the radiation dose and its new progress.
