深圳湾边贸易供应catphan 500 ct模体, phantomlab,ctp500价格优惠！catphan 600, catphan700.
厂家：the phantomlaboratory
模体用来检测ct性能，由塑料制成，它有两个型号，分别是catphan500和catphan600.另外一个是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。
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系统。
