Purpose Our goal were to describe and quantify the difference of time intensity curves in different postion and dosage in rabbits using contrast enhanced power Doppler sonography.Methods After intravenous administration of FX530 as a bolus,dynamic and continuous poewr Doppler sonography images were captured by capture card.The sonography image per second were analyzed for anatomic distribution of contrast agent and changes in mean pixel intensity over time.Results Mean transit time and the distribution volume of the compartment can affect the shape of the time intensity curve at the same dosage.They cause the spreading out of the time intensity curves in A O compared to the time intensity curves obtained from kidney artery and parenchyma kidney.We also found a plateau in signal intensity can be reached a higher concentrations.The curves that correspond to the lower doses,appear to be peaked,whereas those corresponding to the highest doses appear to be smooth,with flattened tops.Conclusion We think it is best to hold the same dosage and equipment condition when we study time intensity curve.As quantitative study the dosage requirement should be following:①Without artifact; ②Peak plateau is the shorter the better; ③It is good idea to find a way to quantify the dynamic process without depending on dosage.

目的经外周静脉团注声学造影剂后,分析不同部位和不同剂量的条件下的能量图时间-强度曲线的变化。方法经外周静脉团注声学造影剂后采取造影前后的不同部位和不同剂量下的动态图像,以每秒一帧进行视频强度分析并绘制时间-强度曲线,并分析不同剂量、部位的曲线形态的差异。结果显示在同一剂量下,不同部位的时间-强度曲线是有变化的。从曲线形态上,空腔灌注血管(动脉)的曲线比实质脏器更为拉伸和延展、增强的持续时间长,实质性组织灌注(肾脏)曲线则相对狭窄。随着剂量的增加,曲线出现“平台期”,任何一部位的时间强度曲线均随剂量的增加而延长。但视频强度的峰值很快便达到饱和,而且并不随着剂量增加而增加。结论在进行时间-强度曲线的定量研究中必须掌握好剂量,对比组之间的剂量务必保持一致,使用剂量应该:①没有溢出伪像;②峰值平台期应该短;③寻找能相对不依赖于剂量的方法是解决定量问题的关键。

On the basis of Similarity Theory, blasting specimen has been built using concrete. Blasting tests have been carried out under the conditions of air and water coupling charges, respectively. Blasting pressure has been measured during the tests and a pressure-duration curve has been obtained. Test results showed that a greater peak pressure has been obtained in the blasting media with water coupling charge. The peak lasted longer, with a low descending speed, and exhibited a peak platform. It was observed that the water coupling charge offers a higher utilization rate of detonation energy,more even distribution of pressure and longer exertion time.With rational blasting parameters, satisfactory results can be obtained for pre-split blasting of water-bearing holes.

根据相似理论 ,用混凝土制作爆破试件 ,并进行了空气耦合和水耦合装药的爆破试验。试验中测量了爆炸压力 ,得出了压力—历时曲线。对测量结果分析表明 ,水耦合装药爆破在被爆介质中产生的爆炸峰值压力较大 ,且持续时间较长、下降相对较慢 ,有峰值平台。这说明水耦合装药爆破的炸药能量利用率高 ,压力均匀 ,作用时间长 ,有利于预裂缝的形成 ,在合理的爆破参数下 ,水孔预裂爆破可取得满意效果。
