Abstract
Using a polystyrene phantom and various concentrations of iodine contrast material, the discrimination of blood vessels by the EMI scanner was studied. Although a 2 mm tube can be delineated using high concentrations of iodine, smaller tubes are not seen due to noise inherent in the system.
摘要
使用聚苯乙烯模型和不同浓度的碘造影剂，对EMI扫描仪辨别血管的能力进行了研究。尽管使用高浓度碘时可以勾勒出2毫米的管道，但由于系统固有的噪声，较小的管道无法看到。
