Time is always used as the most important parameter in the current network security visualization techniques on port scan.This makes the slow scan, the dynamic or random scan, concealed scan and spoofed scan hard to detect, and the detection results of the related security anomalies such as DDoS, worms, Trojans etc are bad too. Therefore, a novel network security visualization method for slow scan, concealed scan etc is proposed in this paper.

目前基于端口扫描的网络安全可视化技术常常以时间作为最重要参数指标，往往只能检测那些较快速地扫描行为，对强动态性、强随机性和强隐蔽性的与端口有关的安全事件如DDoS、蠕虫病毒、木马等效果并不好。

Considering the specialty of pseudo-random vector, a partial scan algorithm for BIST, which unifying the structure analysis and testability analysis, is presented in this paper. Then, the fault simulation experiments on ISCAS89 benchmark circuits by this algorithm is made, and the results, which made by the full scan algorithm and the partial scan algorithm only based on the structure analysis, is compared. The conclusion is achieved: for pseudo-random vector, compared with the full scan circuit and the circuit geted by partial scan algorithm only based on the structure analysis, the circuit geted by our partial scan algorithm can greatly reduce the test time with very close or even greater faults coverage and less area than the full scan.

考虑到伪随机测试向量的特殊性，本文借鉴确定性测试向量生成的部分扫描算法，在内建自测试环境中，提出一种综合结构分析和可测性分析的部分扫描算法，PSBAST，并运用此算法对ISCAS89 benchmark电路进行计算，并对经计算后得到的部分扫描电路进行故障模拟，最后将模拟结果与全扫描电路和一种仅考虑结构因素的部分扫描算法得到的结果进行详细分析和比较，结果表明：对于伪随机测试向量，相对于全扫描电路和由仅考虑结构因素的部分扫描算法得到的电路，本文提出的部分扫描算法得到的电路，能够在不低于全扫描结构故障覆盖率前提下，大幅度减少测试时间，并能降低测试面积开销。

Material and Methods:From March,2008 to January,2009,250 patients(146 Males and 104 Females,ranged from 18 to 82 years old,mean age was 48 years old) enrolled in the First Affiliated Hospital of Kunming Medical College were performed dual energy scan(Group A,200 patients) and Neuro-DSA scan(Group B,50 patients) using DSCT.The patients were randomly divided into Group A and Group B.Regarding to the justification of scan protocol,100 patients in Group A were selected as sub-group to explore the scan protocol.The image quality Was analyzed both in four categories(4.0/60、4.5/60、4.0/70、4.5/70) of flow rate and total amount of contrast-enhanced material and in three categories(100—150HU、150—200HU、200-250HU) of CT value of left common carotid artery.The comparison of two scan approach was based on image quality,radiation does, postprocessing methods,time of scanning and subtraction and data storage amount.To validate the diagnostic capability of DE-CTA virtual unenhanced images,100 patients in Group A were undergoing head scan both in routine non-contrast program and DE-CTA virtual unenhanced program.Mean CT values,signal-to-noise ratio,image quality,sensitivity of lesion identification,and radiation does were applied to comparison.According to diagnostic results of dual energy of cerebral arterial angiography,62 patients out of 200 patients in Group A were confirmed with cerebral vessel lesions,the results were complied with DSA findings(the time between the two methods were within 1 week).

材料与方法收集2008年3月到2009年1月间在昆明医学院第一附属医院行DSCT CTA检查者250例(男性146例，女性104例，年龄范围18-82岁，平均48岁)，随机分为A、B两组，A组200例行双能量头颅CTA扫描；B组50例行Neuro-DSA扫描。A组前100例按对比剂不同流率和总量分为4组(4.0/60、4.5/60、4.0/70、4.5/70)对图像质量比较；按触发时左颈总动脉内平均CT位分3组(100—150HU、150—200HU、200-250HU)，比较图像质量的差异；对A、B两组血管图像质量、辐射剂量、后处理的方法、扫描和后处理时间及数据的容量进行比较分析；A组中前100例行常规与DE-CTA虚拟平扫的平均CT值、信号噪声比、图像质量、病灶显示情况、辐射剂量的比较分析；A组中行DSA检查62例(两种方法间隔时间均1周内)，比较两种检查方法诊断结果是否符合，并对其中24例动脉瘤行动脉瘤部位、数目、形态、瘤颈显示程度、瘤颈大小及瘤体长径和短径的比较研究。
