產(chǎn)品介紹

模體用來檢測醫(yī)院的CT性能,由塑料制成,Catphan500, Catphan600, Catphan5700, CTP500, CTP600, CTP700等. 另外一個(gè)是醫(yī)院的磁共振性能檢測模體,完全使用有機(jī)玻璃制成,也有兩個(gè)型號,其中的圓柱形,就是Magphan® SMR170,廠家是美國模體實(shí)驗(yàn)室。

 

功能:Phantomlab與物理學(xué)家兼哲學(xué)家Goodenough, Ph.D.,共同努力發(fā)展了Catphan®模體。新型的Catphan®模體設(shè)計(jì)是基于醫(yī)療成像儀器方面二十多年的科學(xué)研究和臨床經(jīng)驗(yàn)。該種模體可以應(yīng)用于軸向和螺旋CT掃描成像系統(tǒng)的各種操作評價(jià)以及質(zhì)量保證系統(tǒng)。

 

不同的模塊組成了Catphan®模體,這些模塊尚可適用于連續(xù)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(gòu)成。Solid-cast結(jié)構(gòu)可以降低材料的吸水性和水浴模體相關(guān)的露水問題。

包括Catphan®500在內(nèi)共有三種基本Catphan®模體。Catphan®是為螺旋CT掃描而特殊設(shè)計(jì)的。

包括Catphan®模體的選擇性測試模塊及其標(biāo)

準(zhǔn),經(jīng)常被用于進(jìn)行許多實(shí)驗(yàn)測量。包括以下

一、參數(shù)的評估:

掃描幾何學(xué)(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(yàn)證

病人定位系統(tǒng)驗(yàn)證

supra-slice低對比度靈敏度

subslice低對比度靈敏度

空間均勻性

掃描增量

CT系統(tǒng)噪聲(精度)

圓對稱性

靈敏度(線性)

象素(矩陣)尺寸

動(dòng)態(tài)掃描

X、Y、Z軸的點(diǎn)擴(kuò)散函數(shù)和調(diào)制傳遞函數(shù)(MTF)
