[摘要] 隨著存儲設(shè)備和網(wǎng)絡性能的提高,面向全院的PACS 越來越受到關(guān)注。影像數(shù)據(jù)量大,集中存儲已不能滿足應用的
要求。本文提出一種在全院范圍內(nèi)快速展現(xiàn)病人檢查影像的分布存儲方法:在中心服務器上,存儲影像數(shù)據(jù)的全集;在診斷工作站
和臨床工作站上, 存儲影像數(shù)據(jù)的部分集。病人的檢查影像由分中心服務器依病人檢查申請單的開單科室轉(zhuǎn)發(fā)到相應的分發(fā)服務
器,分發(fā)服務器對接收到的檢查影像全部分發(fā)給管轄的診斷工作站和臨床工作站,工作站上存儲所有收到的檢查影像。文中給出了
實現(xiàn)分布存儲的系統(tǒng)結(jié)構(gòu)。
