摘要：
Optical coherence tomography (OCT) may be used to acquire cross-sectional or volumetric images of any specimen, including biological specimens such as the retina. Additional processing of the OCT data may be performed to generate images of features of interest. In some embodiments, these features may be in motion relative to their surroundings, e.g., blood in the retinal vasculature. In some embodiments, an acquired image may be degraded by motion artifact. The proposed invention describes OCT system embodiments that may be configured for multi-scale imaging, with the capability of switching between low or high lateral resolution, and with the assistance of adaptive optics for aberration correction. The invention also describes a method for enhancing OCT image quality by reducing or eliminating the negative effects introduced by sources and speed by performing bidirectional scanning. The proposed invention describes a method for the combination of images acquired by OCT for the automatic registration and averaging of features, such as blood vessels in images acquired with OCT angiography.
