提出了一种基于强度动态光散射的A线间散斑统计的光学相干层析成像（OCT）非均匀旋转畸变校正新方法。该技术不依赖于组织特征，并且可以对单帧数据执行，从而实现实时图像校正。我们证明了它的适用性，在胃肠道球囊导管OCT系统，确定实际的旋转速度与高时间分辨率，并提出纠正横截面和正面的意见，显示显着增强的图像质量。
We present a new technique for the correction of nonuniform rotation distortion in catheter-based optical coherence tomography (OCT), based on the statistics of speckle between A-lines using intensity-based dynamic light scattering. This technique does not rely on tissue features and can be performed on single frames of data, thereby enabling real-time image correction. We demonstrate its suitability in a gastrointestinal balloon-catheter OCT system, determining the actual rotational speed with high temporal resolution, and present corrected cross-sectional and en face views showing significant enhancement of image quality.
