Methods300case were scanned by contrast-enhanced CT with HPS and the different inject speed, total volume, scan delay time and patient's conditions were analyzed comprehensively.
方法对300例患者用高压注射器进行螺旋CT增强扫描，对不同的注射速度、总量、扫描延迟时间及患者的状况作综合性分析。
Purpose:To deduce the technique parameter like contrast injectional speed, delay time and etc with high pressure injector when carrying out spiral CT scan.
目的：探讨螺旋CT扫描时，高压注射器造影剂的注射速度，延迟时间等技术参数的选择。
The delay in the scan path reduces the need for external buffers to avoid hold-time violations during scan testing of integrated circuits.
该扫描路径上的延迟减少对外部缓冲器的需求，进而在集成电路扫描测试时避免保持时间违反。
