目的探討CT設(shè)備的CT值線性的評價(jià)方法。方法采用Catphan500體模,在相同掃描條件下對43臺CT設(shè)備實(shí)施檢測。對每臺設(shè)備的檢測結(jié)果做1、2階曲線擬合,定義2階擬合曲線的彎曲程度為CT值非線性度,計(jì)算擬合參數(shù)的2-范數(shù)來評價(jià)擬合品質(zhì),計(jì)算擬合直線的斜率及其擬合參數(shù)的2-范數(shù)來評價(jià)對比度標(biāo)度和擬合品質(zhì)。采用MATLAB6.1編程。結(jié)果比較擬合參數(shù)的2-范數(shù),表明2階擬合曲線更符合母體分布規(guī)律;2階擬合曲線的彎曲程度隨直線擬合參數(shù)的2-范數(shù)的增長呈單調(diào)增長趨勢,很好地反映了非線性度。結(jié)論對檢測結(jié)果分別做1、2階曲線擬合,從而定義CT值非線性度和對比度標(biāo)度是符合統(tǒng)計(jì)學(xué)原理的,達(dá)到了定量分析的目的。
