產品介紹

模體(ti)(ti)用來檢(jian)(jian)測(ce)醫院的(de)(de)CT性能(neng),由塑料制成,Catphan500, Catphan600, Catphan5700, CTP500, CTP600, CTP700等. 另外一個(ge)是醫院的(de)(de)磁共振性能(neng)檢(jian)(jian)測(ce)模體(ti)(ti),完全使用有機玻(bo)璃制成,也有兩個(ge)型號,其中的(de)(de)圓柱形,就是Magphan® SMR170,廠(chang)家是美(mei)國模體(ti)(ti)實驗室。

 

功能:Phantomlab與物理學(xue)家兼哲學(xue)家Goodenough, Ph.D.,共同努(nu)力發(fa)展了(le)Catphan®模(mo)(mo)體(ti)。新型的Catphan®模(mo)(mo)體(ti)設計是基于醫療成(cheng)像儀器方(fang)面二十(shi)多年的科學(xue)研究和(he)臨(lin)床經驗。該種模(mo)(mo)體(ti)可以(yi)應用于軸向和(he)螺旋CT掃描成(cheng)像系(xi)統的各種操(cao)作評價以(yi)及質量保證系(xi)統。

 

不同(tong)的(de)模(mo)塊組成了(le)Catphan®模(mo)體,這些模(mo)塊尚可(ke)(ke)適用(yong)于連續20cm空(kong)間。為了(le)在(zai)Catphan®424中使用(yong)水(shui)(shui)(shui)容器,所有Catphan®組件都是由Solid-cast材料構成。Solid-cast結構可(ke)(ke)以降低材料的(de)吸水(shui)(shui)(shui)性和(he)水(shui)(shui)(shui)浴模(mo)體相關的(de)露水(shui)(shui)(shui)問題。

包括Catphan®500在內共(gong)有(you)三種基本Catphan®模體(ti)。Catphan®是為螺旋CT掃(sao)描而(er)特殊(shu)設計的。

包括Catphan®模體(ti)的選擇性(xing)測(ce)試模塊(kuai)及其標

準(zhun),經(jing)常被用于(yu)進行許多實驗(yan)測量。包括(kuo)以下
