美国Catphan500CT性能测试医疗模体
产品编号:2013627105853
产品描述:美国Catphan 500 CT性能测试模体已得到全球知名CT生产公司的认同,都用它来标示CT机的成像性能。该模体较依据AAPM 1977年1号报告生产加工的注水模体有很多优点:因是固体模体,没有漏水的问题;储运箱能当模体支架,模体能探出扫描床外;低对比度分辨力模体由同一种物质不同密度材料制成等。
厂家:The Phantom Laboratory

产品介绍
医疗模体:

模体用来检测医院的CT性能,由塑料制成,Catphan500, Catphan600, Catphan5700, CTP500, CTP600, CTP700等. 另外一个是医院的磁共振性能检测模体,完全使用有机玻璃制成,也有两个型号,其中的圆柱形,就是Magphan® SMR170,厂家是美国模体实验室。
功能:Phantomlab与物理学家兼哲学家Goodenough, Ph.D.,共同努力发展了Catphan®模体。新型的Catphan®模体设计是基于医疗成像仪器方面二十多年的科学研究和临床经验。该种模体可以应用于轴向和螺旋CT扫描成像系统的各种操作评价以及质量保证系统。
不同的模块组成了Catphan®模体,这些模块尚可适用于连续20cm空间。为了在Catphan®424中使用水容器,所有Catphan®组件都是由Solid-cast材料构成。Solid-cast结构可以降低材料的吸水性和水浴模体相关的露水问题。
包括Catphan®500在内共有三种基本Catphan®模体。Catphan®是为螺旋CT扫描而殊设计的。
包括Catphan®模体的选择性测试模块及其标
