美國(guó)phantomlab Catphan500 CT性能測(cè)試體膜產(chǎn)品簡(jiǎn)介：

美國(guó)Catphan 500 CT性能測(cè)試模體已得到全球知名CT生產(chǎn)公司的認(rèn)同，都用它來(lái)標(biāo)示CT機(jī)的成像性能。該模體較依據(jù)AAPM 1977年1號(hào)報(bào)告生產(chǎn)加工的注水模體有很多優(yōu)點(diǎn)：因是固體模體，沒(méi)有漏水的問(wèn)題；儲(chǔ)運(yùn)箱能當(dāng)模體支架，模體能探出掃描床外；低對(duì)比度分辨力模體由同一種物質(zhì)不同密度材料制成等。
