Hiscan VM Pro是一款快速靈活的活體顯微CT，主要用于動(dòng)物實(shí)驗(yàn)。其所用的錐束X射線可以看到樣本的內(nèi)部結(jié)構(gòu)，最高分辨率可達(dá)18μm。可做小動(dòng)物全身掃描，如小鼠、大鼠等。同時(shí)，可以掃描所選擇的感興趣區(qū)域，例如小鼠和大鼠的頭部、脊椎、前肢 、后肢等。根據(jù)樣本尺寸不同配以不同尺寸的掃描床，獨(dú)特設(shè)計(jì)的掃描床可以防止小動(dòng)物逃逸落進(jìn)機(jī)器內(nèi)。

　　Hiscan VM Pro配有高精度自適應(yīng)呼吸門控，可根據(jù)呼吸周期的變化動(dòng)態(tài)調(diào)整圖像采集速度，有效減少呼吸帶來的胸廓運(yùn)動(dòng)偽影。防護(hù)機(jī)殼配有麻醉氣體傳輸接口以及多種生理監(jiān)控設(shè)備接口。X射線機(jī)殼防護(hù)安全可靠，操作人員無需額外防護(hù)。同時(shí)配有安全連鎖裝置，倉(cāng)門打開時(shí)自動(dòng)關(guān)閉X射線，避免誤操作，保證操作人員安全。

       廣泛應(yīng)用于骨骼疾病、腫瘤疾病、心血管疾病、炎癥疾病、代謝疾病、免疫學(xué)、藥效評(píng)價(jià)、生物材料等學(xué)科的臨床前研究。

　? 高精度呼吸門控

　　通過高精度呼吸門控采集呼吸信號(hào)，根據(jù)呼吸信號(hào)波形進(jìn)行圖像采集獲得同一呼吸相位的圖像，從而消除呼吸運(yùn)動(dòng)帶來的偽影，獲得清晰的重建圖像。同時(shí)具有自適應(yīng)性，根據(jù)不同小鼠的呼吸頻率自動(dòng)調(diào)整圖像采集速度，智能掃描。

　? 精密設(shè)計(jì)掃描床

　　經(jīng)過精密設(shè)計(jì)的掃描床，操作方便，小動(dòng)物放置在前部透明掃描倉(cāng)內(nèi)，配有攝像頭監(jiān)控小動(dòng)物呼吸;同時(shí)配有麻醉氣體接口，保證小鼠呼吸穩(wěn)定;另外還配有造影劑持續(xù)注射接口，可持續(xù)造影，用于灌注成像。

   ? 多模態(tài)圖像融合技術(shù)

　　為多模態(tài)圖像融合設(shè)計(jì)獨(dú)特配準(zhǔn)裝置，掃描床上有特定標(biāo)記位點(diǎn)，在多種設(shè)備上均可成像，根據(jù)這些特定標(biāo)記位點(diǎn)進(jìn)行圖像配準(zhǔn)融合。

　? GPU加速快速分層重建

　　采用經(jīng)過優(yōu)化的快速分層重建算法，并使用GPU進(jìn)行硬件加速，重建速度提高到掃描結(jié)束重建同時(shí)完成。
