Hiscan VM Pro是一款快速靈活的活體顯微CT，主要用于動物實驗。其所用的錐束X射線可以看到樣本的內部結構，最高分辨率可達18μm。可做小動物全身掃描，如小鼠、大鼠等。同時，可以掃描所選擇的感興趣區域，例如小鼠和大鼠的頭部、脊椎、前肢 、后肢等。根據樣本尺寸不同配以不同尺寸的掃描床，獨特設計的掃描床可以防止小動物逃逸落進機器內。

　　Hiscan VM Pro配有高精度自適應呼吸門控，可根據呼吸周期的變化動態調整圖像采集速度，有效減少呼吸帶來的胸廓運動偽影。防護機殼配有麻醉氣體傳輸接口以及多種生理監控設備接口。X射線機殼防護安全可靠，操作人員無需額外防護。同時配有安全連鎖裝置，倉門打開時自動關閉X射線，避免誤操作，保證操作人員安全。

       廣泛應用于骨骼疾病、腫瘤疾病、心血管疾病、炎癥疾病、代謝疾病、免疫學、藥效評價、生物材料等學科的臨床前研究。

　? 高精度呼吸門控

　　通過高精度呼吸門控采集呼吸信號，根據呼吸信號波形進行圖像采集獲得同一呼吸相位的圖像，從而消除呼吸運動帶來的偽影，獲得清晰的重建圖像。同時具有自適應性，根據不同小鼠的呼吸頻率自動調整圖像采集速度，智能掃描。

　? 精密設計掃描床

　　經過精密設計的掃描床，操作方便，小動物放置在前部透明掃描倉內，配有攝像頭監控小動物呼吸;同時配有麻醉氣體接口，保證小鼠呼吸穩定;另外還配有造影劑持續注射接口，可持續造影，用于灌注成像。

   ? 多模態圖像融合技術

　　為多模態圖像融合設計獨特配準裝置，掃描床上有特定標記位點，在多種設備上均可成像，根據這些特定標記位點進行圖像配準融合。

　? GPU加速快速分層重建

　　采用經過優化的快速分層重建算法，并使用GPU進行硬件加速，重建速度提高到掃描結束重建同時完成。
