摘要
双源CT的出现解决了传统多层CT技术不能解决的问题,是CT领域十分重要的进展,将指引CT新的发展方向。西门子SOMATOM Definition Flash系统通过二套X射线源和探测器,完成心脏扫描,独特的双能量技术可以对心率过快、不规则心率及屏气有困难的患者进行扫描,克服了传统64层CT需要服药控制心率的弊端。图像质量明显提高,比常规CT具有更多的优势和临床应用功能,同时还可进行其它方面的成像研究。
The development of double source CT is an important advancement in CT technology since it can solve those problems that can not be solved by conventional multi-slice CT. Through two sets of X-ray source and detector, Siemens SOMATOM Definition Flash the system can show the details of the heart SOMATOM Definition Flash with 75 ms time resolution. Dual-source CT image quality is significantly improved compared with conventional CT. Dual Source CT can be used in patients with fast heart rate, irregular heart rate and breath holding.Dual Source CT can clearly show the coronary artery, so it can be used for multi-slice reconstruction.
