產品介紹
模體用來檢測醫院的CT性能,由塑料制成,Catphan500, Catphan600, Catphan5700, CTP500, CTP600, CTP700等. 另外一個是醫院的磁共振性能檢測模體,完全使用有機玻璃制成,也有兩個型號,其中的圓柱形,就是Magphan® SMR170,廠家是美國模體實驗室。
功能:Phantomlab與物理學家兼哲學家Goodenough, Ph.D.,共同努力發展了Catphan®模體。新型的Catphan®模體設計是基于醫療成像儀器方面二十多年的科學研究和臨床經驗。該種模體可以應用于軸向和螺旋CT掃描成像系統的各種操作評價以及質量保證系統。
不同的模塊組成了Catphan®模體,這些模塊尚可適用于連續20cm空間。為了在Catphan®424中使用水容器,所有Catphan®組件都是由Solid-cast材料構成。Solid-cast結構可以降低材料的吸水性和水浴模體相關的露水問題。
包括Catphan®500在內共有三種基本Catphan®模體。Catphan®是為螺旋CT掃描而特殊設計的。
包括Catphan®模體的選擇性測試模塊及其標
