【摘要】 目的模拟建立计算局部组织灌注量差异性的方法。材料和方法:应用电子束CT扫描检查,通过体外模型产生一个相似于静注造影剂后体内过程中的灌注曲线,对不同容积的组织区同时灌注,观察、分析不同灌注量时曲线变化的特征和规律。结果:通过适当调节该模型可产生与造影剂静注后在体内相似的变化曲线。更多还原

【Abstract】 A Variate curve deviced for an indicator - dilution in human body will be produced when a bolus injection of contrast medium is passing through an enlarged container. With specially connected vitreous boxes and canals to simulate both tissue and vessels, EBCT was used on flow programme to measure flows in this construction, A linear - shaped segment of the beginning of risen curve was chosen according to the first 5-7 scan values and its slopes were calculated and compared.更多还原
