	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 

	美国Catphan 500 CT性能测试医疗模体,性能测试医疗模体 500CT,Catphan性能测试医疗模体产品介绍:

	 

	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扫描而特殊设计的。

	 

	包括Catphan?模体的选择性测试模块及其标
