摘要
阐述了双源CT的技术原理及其临床应用。通过对双源CT特殊结构及工作原理的分析和讨论,并结合临床的实际应用验证,证明了双源CT时间分辨率高,心血管的成像不受心率的限制;X线吸收剂量低,具有更高的安全性;图像空间分辨率及信噪比更高,可提供更可靠的临床依据;具有独特的双能量技术,可进行功能代谢等方面的检查和研究等。指出双源CT比常规CT具有更多优势的功能和应用。
The structure and working principle of dual-source CT(DSCT) and its clinic application are expatiated. Many advantages are proved after the analysis and discussion and also after the validation of clinic application, such as higher temporal resolution for the imaging of cardiac and coronary artery to be finished without the influence of any heart rate, lower X-ray absorbing dose to offer more safe surrounding for the patients, higher special resolution and higher signal to noise of images to offer more reliable diagnostic tool, the technology of dual-energy is special in the examination and research of function and metabolize of human being.
