美國RSDRS-240血管造影頭部模體填補(bǔ)了物理和解剖信息需求之間的差距。在組織等效材料模型中,精確的男性顱骨包含三維 高對(duì)比度血管模擬,以促進(jìn)放射科醫(yī)師對(duì)血管造影圖像質(zhì)量的主觀評(píng)估與在相同暴露條件下實(shí)際測量分辨率和對(duì)比度的相關(guān)性。
每個(gè)RSDRS-240血管造影頭部模體包含一個(gè)5步楔形。2-10線對(duì)/mm測試圖案是可選的。其他模式或測試對(duì)象和自定義病理可以按照特殊順序提供。

RS-240血管造影頭部模體提供了一個(gè)“空運(yùn)行”,以完全檢查血管造影設(shè)備,并確保在對(duì)患者進(jìn)行放射性程序之前,在所有重要細(xì)節(jié)上都能令人滿意地運(yùn)行。
如果成像系統(tǒng)發(fā)生故障,幻像在隔離和驗(yàn)證糾正問題方面也起著至關(guān)重要的作用。血管造影頭影像將變量局限于組件和技術(shù),是一種寶貴的服務(wù)和教學(xué)工具。
獨(dú)特的RSD軟組織等效材料被用于皮膚組織和頸部,并被調(diào)整為顱內(nèi)的腦密度。這種材料在放射性吸收和散射特性中密切重復(fù)腦組織。模體幾乎是防碎的。
高對(duì)比度的三維血管圖案被放置在中間平面中。該模式在其早期階段與內(nèi)部頸動(dòng)脈動(dòng)脈造影非常相似。血管造影模式的放射密度已被調(diào)整為代表75%的造影劑?;孟罂梢匀轿皇褂?。
血管造影頭像可以是全頭或半頭。完整的頭部具有代表人體頭部的全散射特性和主體對(duì)比度的優(yōu)點(diǎn)。半頭模型非常適合非網(wǎng)格技術(shù)。它具有重量更輕,成本更低,尺寸更小的優(yōu)點(diǎn),可以輕松裝入公文包中。
模擬血管圖案,分辨率圖和stepwedge的組合使得用戶能夠?qū)⑽锢韰?shù)(例如分辨率,對(duì)比度和速度)與顱骨標(biāo)記和血管細(xì)節(jié)的主觀評(píng)估相關(guān)聯(lián)。
RSDRS-240血管造影頭部模體有透明或不透明的型號(hào)。
