光谱域光学相干层析成像(SD-OCT)是诊断各种视网膜疾病的重要工具。SD-OCT体积的测量可用于在导致的视力损失变得明显之前检测青光眼患者的结构变化。成像过程中的眼球运动会破坏数据，使测量结果不可靠。我们提出了一种方法来校正扫描采集后SD-OCT体积中的横向运动伪影，方法是将体积配准到瞬时的无伪影的参考图像中。我们的手术矫正了由眼球震颤和漂移引起的平滑变形，以及由微眼跳引起的血管的突然中断。我们在48个健康眼睛和116个青光眼扫描上测试了我们的性能，在96%的健康眼睛和73%的青光眼中提高了扫描质量。
Spectral domain optical coherence tomography (SD-OCT) is an important tool for the diagnosis of various retinal diseases. The measurements available from SD-OCT volumes can be used to detect structural changes in glaucoma patients before the resulting vision loss becomes noticeable. Eye movement during the imaging process corrupts the data, making measurements unreliable. We propose a method to correct for transverse motion artifacts in SD-OCT volumes after scan acquisition by registering the volume to an instantaneous, and therefore artifact-free, reference image. Our procedure corrects for smooth deformations resulting from ocular tremor and drift as well as the abrupt discontinuities in vessels resulting from microsaccades. We test our performance on 48 scans of healthy eyes and 116 scans of glaucomatous eyes, improving scan quality in 96% of healthy and 73% of glaucomatous eyes.
