產品介(jie)紹

模體用來檢測醫院的CT性(xing)能(neng),由(you)塑料制成,Catphan500, Catphan600, Catphan5700, CTP500, CTP600, CTP700等. 另外(wai)一個是醫院的磁共振(zhen)性(xing)能(neng)檢測模體,完全使用有機玻璃(li)制成,也(ye)有兩個型號(hao),其中的圓柱形,就是Magphan® SMR170,廠家是美國(guo)模體實(shi)驗室(shi)。

 

功能:Phantomlab與(yu)物理學(xue)家兼哲學(xue)家Goodenough, Ph.D.,共同努力發(fa)展了Catphan®模(mo)體。新型的(de)(de)Catphan®模(mo)體設(she)計是基于醫療(liao)成(cheng)像(xiang)儀器方面二十多年的(de)(de)科學(xue)研究和臨(lin)床經驗(yan)。該種模(mo)體可以應用(yong)于軸向和螺(luo)旋CT掃描成(cheng)像(xiang)系統的(de)(de)各種操(cao)作評價以及(ji)質量保證系統。

 

不同的(de)(de)模(mo)(mo)塊組(zu)成了(le)Catphan®模(mo)(mo)體(ti),這(zhe)些模(mo)(mo)塊尚可適用于(yu)連續(xu)20cm空(kong)間(jian)。為了(le)在Catphan®424中(zhong)使用水容器,所(suo)有(you)Catphan®組(zu)件都是由Solid-cast材(cai)料(liao)(liao)構成。Solid-cast結構可以降低材(cai)料(liao)(liao)的(de)(de)吸水性和水浴模(mo)(mo)體(ti)相關的(de)(de)露水問題(ti)。

包括(kuo)Catphan®500在(zai)內共(gong)有(you)三種基本(ben)Catphan®模(mo)體(ti)。Catphan®是為(wei)螺(luo)旋CT掃描而特殊設計的。

包括Catphan®模體的選擇性測(ce)試模塊及其標

準(zhun),經常被用于進行許多實驗測量。包(bao)括以(yi)下
