　　Hiscan VM Pro配有高精度自適應呼吸門控，可根據(jù)呼吸周期的變化動態(tài)調(diào)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(jiān)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(guān)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(jù)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(jù)不同小鼠的呼吸頻率自動調(diào)整圖像采集速度，智能掃描。

　? 精密設計掃描床

　　經(jīng)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(nèi)，配有攝像頭監(jiān)控小動物呼吸;同時配有麻醉氣體接口，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(jù)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(jīng)過優(yōu)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(jié)束重建同時完成。
