| 摘 要： | 目的:探讨双源CT扫描参数对影像质量的影响及影像质量的控制。方法:使用西门子(SOMATOM)Definition Flash双源CT,在扫描时设置不同的扫描参数对受检者进行扫描,并对扫描影象加以对比。结果:发现双源CT影像的质量与性能,可以通过设置相关扫描参数以及受检者人为因素的改变而使影像质量随之得到改变。结论:各种扫描参数的设置与影像质量密切相关,有时可能因影像质量的降低而给临床诊断造成误差,因此必须合理优化检查方案,选择恰当的扫描参数以保证影象质量,从而满足临床诊断的准确性。

| Abstract: | Objective:To study the effect of dual source CT scanning parameters on image quality. Method:The Siemens SOMATOM Definition Flash dual-source CT was used. We set different scanning parameters and scanning time to scan the client and compared the scanned image. Result:The image quality and performance of the dual source CT depended on setting of the scanning time and the client's human factors. Conclusion:The various settings for the scan parameter are closely related to image quality. Sometimes, it may redu... |
