產品介紹

模(mo)體用來檢(jian)測醫院(yuan)(yuan)的CT性能(neng),由(you)塑(su)料制成(cheng),Catphan500, Catphan600, Catphan5700, CTP500, CTP600, CTP700等. 另外一個(ge)是醫院(yuan)(yuan)的磁共(gong)振性能(neng)檢(jian)測模(mo)體,完全使用有機玻璃制成(cheng),也(ye)有兩個(ge)型號,其中的圓柱形,就是Magphan® SMR170,廠家是美國模(mo)體實驗室。

 

功能:Phantomlab與物理學(xue)家兼哲(zhe)學(xue)家Goodenough, Ph.D.,共同努(nu)力發(fa)展(zhan)了Catphan®模(mo)體。新型的Catphan®模(mo)體設計(ji)是基于(yu)(yu)醫療成像儀器方面二十多年的科(ke)學(xue)研究和臨床經驗。該種模(mo)體可(ke)以應用于(yu)(yu)軸向和螺旋(xuan)CT掃(sao)描成像系(xi)(xi)統的各種操作評價(jia)以及質量保證系(xi)(xi)統。

 

不同的(de)(de)模塊(kuai)組成了(le)Catphan®模體(ti),這些模塊(kuai)尚可適用(yong)于連(lian)續20cm空間(jian)。為了(le)在(zai)Catphan®424中(zhong)使用(yong)水容器,所有Catphan®組件都(dou)是由Solid-cast材料(liao)構成。Solid-cast結構可以降低材料(liao)的(de)(de)吸水性和水浴模體(ti)相關的(de)(de)露水問題。

包(bao)括Catphan®500在內共有三種(zhong)基本Catphan®模(mo)體。Catphan®是為螺旋(xuan)CT掃(sao)描而特殊設計(ji)的。

包括Catphan®模(mo)體的選擇性測(ce)試模(mo)塊及其標

準,經常被用于進行許多(duo)實驗測量。包括以下

一、參數的評估:

掃描幾(ji)何學(層寬和靈敏度曲線)

高分辨率(最高至20線對/厘米)

體模定位驗證

病人定位系統驗證

supra-slice低對比度靈敏度

subslice低(di)對比度靈敏度

空間均勻性

掃描增量

CT系統噪聲(精度(du))

圓對稱性

靈敏度(線性)

象素(矩陣)尺寸

動態掃描

X、Y、Z軸(zhou)的點擴散函數(shu)和調(diao)制(zhi)傳遞(di)函數(shu)(MTF)
