產品介紹

模體(ti)用來(lai)檢測(ce)(ce)醫院的(de)CT性(xing)能,由塑料制(zhi)(zhi)成,Catphan500, Catphan600, Catphan5700, CTP500, CTP600, CTP700等(deng). 另外一(yi)個是醫院的(de)磁(ci)共(gong)振性(xing)能檢測(ce)(ce)模體(ti),完全(quan)使用有機(ji)玻璃制(zhi)(zhi)成,也有兩(liang)個型號,其中的(de)圓柱(zhu)形,就是Magphan® SMR170,廠(chang)家是美國模體(ti)實(shi)驗室。

 

功(gong)能:Phantomlab與物理(li)學(xue)(xue)(xue)家兼(jian)哲學(xue)(xue)(xue)家Goodenough, Ph.D.,共同(tong)努力發展了Catphan®模(mo)體。新型的Catphan®模(mo)體設計(ji)是基于醫療成像(xiang)儀器(qi)方(fang)面二(er)十多年的科學(xue)(xue)(xue)研究和(he)臨床經驗。該(gai)種模(mo)體可以應用于軸向和(he)螺旋(xuan)CT掃描成像(xiang)系統的各種操作(zuo)評(ping)價以及質(zhi)量保證系統。

 

不同(tong)的模(mo)塊組(zu)(zu)成了(le)Catphan®模(mo)體,這些模(mo)塊尚(shang)可(ke)適用(yong)于連續20cm空間。為了(le)在Catphan®424中使用(yong)水(shui)容器(qi),所有(you)Catphan®組(zu)(zu)件都是由Solid-cast材料(liao)構成。Solid-cast結構可(ke)以(yi)降低材料(liao)的吸水(shui)性和(he)水(shui)浴(yu)模(mo)體相關(guan)的露(lu)水(shui)問題。

包括Catphan®500在(zai)內共(gong)有三種(zhong)基本Catphan®模體。Catphan®是為螺旋CT掃(sao)描而特殊設計的。

包(bao)括Catphan®模體的選擇性測試模塊及其標

準,經常被用于(yu)進行許多(duo)實驗測量。包括以下

一、參數的評估:

掃描幾何學(xue)(層寬(kuan)和靈(ling)敏度曲線)

高分辨率(lv)(最高至20線對(dui)/厘米(mi))

體模定位驗證

病人定位系統驗證

supra-slice低對比度(du)靈敏度(du)

subslice低對比度(du)靈敏度(du)

空間均勻性

掃描增量

CT系統噪聲(sheng)(精度)

圓對稱性

靈敏度(線性)

象素(矩陣)尺寸

動態掃描

X、Y、Z軸的點(dian)擴散函數和調制傳遞函數(MTF)
