產(chan)品介紹(shao) 

模體用(yong)來檢測(ce)醫院的(de)CT性能(neng)(neng),由塑料(liao)制(zhi)成,Catphan500, Catphan600, Catphan5700, CTP500, CTP600, CTP700等. 另外一個是(shi)(shi)醫院的(de)磁共振性能(neng)(neng)檢測(ce)模體,完全(quan)使用(yong)有機(ji)玻璃制(zhi)成,也有兩個型號(hao),其(qi)中(zhong)的(de)圓柱(zhu)形,就是(shi)(shi)Magphan® SMR170,廠家是(shi)(shi)美國模體實驗室。

 

功能(neng):Phantomlab與物理學家(jia)(jia)兼哲學家(jia)(jia)Goodenough, Ph.D.,共(gong)同努力發展(zhan)了Catphan®模(mo)體(ti)。新型的Catphan®模(mo)體(ti)設(she)計是基于醫療成像儀器方面二十多(duo)年的科學研究和臨床經驗。該(gai)種(zhong)模(mo)體(ti)可以應用于軸向和螺旋CT掃描成像系統的各種(zhong)操作評價以及質(zhi)量保證系統。

 

不同的(de)(de)模塊(kuai)(kuai)組(zu)成了(le)Catphan®模體,這些(xie)模塊(kuai)(kuai)尚可適用于連續20cm空間。為了(le)在Catphan®424中使用水容(rong)器(qi),所有Catphan®組(zu)件(jian)都(dou)是由Solid-cast材料構成。Solid-cast結構可以降低材料的(de)(de)吸(xi)水性和水浴(yu)模體相關的(de)(de)露水問(wen)題。

包括(kuo)Catphan®500在內共有三種基本(ben)Catphan®模體。Catphan®是(shi)為螺旋CT掃描而特殊(shu)設計的。

包括(kuo)Catphan®模(mo)體的(de)選擇性測試模(mo)塊及其標

準,經(jing)常被(bei)用于進行(xing)許多實驗測量。包括以(yi)下
