摘要:
The present invention is directed to a method and system for improved aiming during Optical Coherence Tomography (OCT) on young children and those unable to cooperate with OCT imaging by synchronization with retinal birefringence scanning (RBS). OCT is performed without knowing whether or not the subject is looking at the intended target. The present invention combines OCT retinal imaging, such as, but not limited to, time domain OCT, SDOCT, or SSOCT, with RBS technology that provides accurate information on the presence or absence of foveal fixation. Therefore, the present invention only analyzes data during foveal fixation. A system combining OCT with RBS is implemented such that both systems co-operate in a specified alignment, such that when the RBS fixation detection system detects alignment with the fovea of the eye, the OCT system will be aimed at the retinal region of interest, usually but not necessarily including the macular area.
