摘要

我们研发了一种新型的血管内光学相干成像术(IV-OCT),该技术能极其快速地实现冠状动脉成像,并通过消除心脏运动伪影和欠采样以实现图像的更高质量。它所依赖的成像探头包括一个直径为1.0 mm 且转速为5600 rev·s–1的同步微电机,使IV-OCT 的帧频达到5.6 kHz,并使用每秒产生280 万图像扫描线的波长扫描激光器。通过使用该设备,我们团队在设置速度为100 mm·s–1时实现了体外5600 fps 和体内4000 fps 的成像速度。由实验对象的心电图触发整个图像采集过程,当心脏在跳动过程中相对不强烈时扫描冠状动脉,因此该技术还有一个新名字,"心动光学相干成像术"(Heartbeat OCT)。
