Indus 超聲多普勒血流系統(tǒng) (DFVS) 是一項(xiàng)技術(shù)成熟且能夠大幅度消減實(shí)驗(yàn)成本并取代傳統(tǒng)成像技術(shù)的系統(tǒng)。小型手持式探針能夠輕松、穩(wěn)定地測(cè)量小動(dòng)物心臟血液流動(dòng)情況,成功提高心臟動(dòng)脈研究效率。
多普勒血流系統(tǒng)采用了高頻多普勒脈沖探測(cè)裝置,能通過(guò)專業(yè)的集成數(shù)據(jù)分析軟件分析小動(dòng)物心血管功能狀況。其高采集頻率所帶來(lái)的高成像分辨率使得它能夠成為研究小鼠及其他小動(dòng)物心臟血流速度的理想工具。
該系統(tǒng)由三部分裝置組成: 脈沖多普勒收發(fā)器(PDT: 10 & 20 MHz 可切換雙通道系統(tǒng)),多普勒信號(hào)數(shù)字采集器 (DSD),和多普勒工作站軟件 (DW)。
產(chǎn)品特征
連續(xù)的測(cè)量與反饋以保障測(cè)量的準(zhǔn)確性
可以在不同條件下評(píng)估心臟收縮與舒張功能
可以通過(guò)比較左右頸動(dòng)脈速度判斷主動(dòng)脈狹窄(TAC)情況
壓力灰階能夠估計(jì)主動(dòng)脈狹窄TAC的血流速度
測(cè)量充血速度評(píng)估冠狀動(dòng)脈血流的儲(chǔ)備,而心臟功能會(huì)受到疾病、年齡、壓力/體積的影響
冠狀動(dòng)脈血流分布可以通過(guò)收縮壓/舒張壓流動(dòng)比率的變化體現(xiàn)
