產品介紹

模體用(yong)(yong)來檢測醫(yi)院(yuan)的(de)CT性能(neng),由塑料(liao)制成,Catphan500, Catphan600, Catphan5700, CTP500, CTP600, CTP700等. 另外一(yi)個是(shi)醫(yi)院(yuan)的(de)磁(ci)共振性能(neng)檢測模體,完全使用(yong)(yong)有(you)機(ji)玻璃制成,也有(you)兩個型號,其中的(de)圓柱(zhu)形(xing),就(jiu)是(shi)Magphan® SMR170,廠家是(shi)美(mei)國模體實驗室(shi)。

 

功能:Phantomlab與物理(li)學家兼哲學家Goodenough, Ph.D.,共(gong)同努(nu)力發展(zhan)了Catphan®模(mo)體。新(xin)型的Catphan®模(mo)體設計是(shi)基于醫療成(cheng)像(xiang)(xiang)儀器方面二十多年的科學研究(jiu)和(he)臨床(chuang)經(jing)驗(yan)。該種模(mo)體可以應用于軸向和(he)螺旋CT掃(sao)描成(cheng)像(xiang)(xiang)系統的各種操作評價以及(ji)質量保證系統。

 

不同的模(mo)(mo)塊(kuai)組成(cheng)了(le)Catphan®模(mo)(mo)體(ti),這些模(mo)(mo)塊(kuai)尚可適用于連續20cm空(kong)間。為(wei)了(le)在Catphan®424中使用水容器,所有Catphan®組件都是由Solid-cast材料構成(cheng)。Solid-cast結構可以降低材料的吸水性(xing)和水浴模(mo)(mo)體(ti)相關(guan)的露水問題。

包括Catphan®500在內(nei)共有三種基本Catphan®模體。Catphan®是為螺旋CT掃描(miao)而特殊(shu)設計的。

包括Catphan®模(mo)體的(de)選擇性測試模(mo)塊(kuai)及其(qi)標

準,經常(chang)被用(yong)于進行(xing)許(xu)多實驗測量(liang)。包括以下

一、參數的評估:

掃描幾何學(層(ceng)寬和(he)靈敏度曲線)

高分辨率(最高至20線對(dui)/厘米)

體模定位驗證

病人定位系統驗證

supra-slice低對(dui)比(bi)度靈(ling)敏度

subslice低(di)對比度(du)(du)靈敏度(du)(du)

空間均勻性

掃描增量

CT系統噪(zao)聲(精度)

圓對稱性

靈敏度(線性)

象素(矩陣)尺寸

動態掃描

X、Y、Z軸的(de)點(dian)擴散函數和調制(zhi)傳遞函數(MTF)
