Accuracy between two groups was calculated byχ~2 test.Calculate the average effective radiation dose of the 30 patients.Results In group A,seventeen patients underwent both DSCT coronary angiography and SCAG,among 255 segments of 17 patients,105 lesion sites of 70 segments were diagnosed stenosis or obstruction,of them,95 lesion sites were confirmed by SCAG.The accuracy of DSCTCA was 90.48%.The agreement of two methods have a high agreement(Kappa =0.853).In group B,13 patients underwent both DSCT coronary angiography and SCAG,among 195 segments of 13 patients,73 lesion sites of 57 segments were diagnosed stenosis or obstruction, of them,65 lesion sites were confirmed by SCAG.The accuracy of DSCTCA was 89.04%.The agreement of two methods have a high agreement(Kappa =0.835). There was no significant difference(χ~2=0.098,p＞0.05) between the accuracy of two groups.The effective radiation dose of 30 patients was 3.67±0.43 mSv.Conclusion Compared with SCAG,prospectively ECG-gated transverse DSCT is a valuable examination to detect and diagnose coronary artery disease with a low dose coronary angiography.The accuracy of the DSCT is approximate to the SCAG.There was no significant difference between the accuracy of two groups.

结果200例患者均成功完成了适应性前瞻性心电门控双源CT冠状动脉血管成像；30例同期行SCAG检查的患者，A组17例：HR≤75 bpm，可评价冠状动脉节段255个，70个冠状动脉节段有105处不同程度的狭窄，95处狭窄程度与金标准SCAG相符，其阳性诊断准确率为90.48%；2种方法的诊断结果得到了较高的一致性(Kappa值=0.853)。B组13例；HR≥91 bpm，可评价冠状动脉节段195个，57个冠状动脉节段有73处不同程度的狭窄，65处狭窄程度与SCAG相符，其阳性诊断准确率为89.04%；2种方法的诊断结果得到了较高的一致性(Kappa值=0.835)。2个心率组间的诊断准确率无明显统计学差异(x~2=0.098，p＞0.05)。30例患者的平均有效辐射剂量为3.67±0.43 mSv结论适应性前瞻性心电门控双源CT冠状动脉成像是一种有效减低辐射剂量的扫描方式，其诊断准确率与金标准SCAG相比得到较高的一致性，且高、低2个心率组间诊断准确率无明显统计学差异。

Bipartite matching is adopted to adjust the relations between the constraint equations and variables, and then the matching result is mapped to a data structure named Engineering Constraint Graph. A solving sequence is achieved by topology sort and strong connected component condensation of ECG.

先使用二分图最大匹配调整约束方程与自变量之间的匹配关系，然后将匹配结果映射为工程约束图，通过对工程约束图进行强连通分量凝聚和拓扑排序，得到求解序列。

15 And 20-22 weeks old SHR with implanted radiotelemetry devices were intratracheally administered with both normal saline and SRM 2975 (500 μg/animal, n=3) or (A-DEP 500 μg/animal, n=3) alternatively, so each rat could serve as its own control. ECG signals were recorded for 72 hours after each exposure, and heart rate and parameters of HRV including standard deviation of normal-to-normal intervals and root mean square of successive differences of adjacent normal-to-normal intervals were analyzed.
