FORMALIZATION OF RETINAL NERVE FIBER LAYER THICKNESS MEASUREMENTS MADE BY TIME DOMAIN-OPTICAL COHERENCE TOMOGRAPHY
摘要
A scan location matching (SLM) method identifies conventional time domain optical coherence tomography (TD-OCT) circle scan locations within three-dimensional spectral domain OCT scan volumes. A technique uses both the SLM algorithm and a mathematical retinal nerve fiber bundle distribution (RNFBD) model, which is a simplified version of the anatomical retinal axon bundle distribution pattern, to normalize TD-OCT thickness measurements for the retinal nerve fiber layer (RNFL) of an off-centered TD-OCT circle scan to a virtual location, centered on the optic nerve head. The RNFBD model eliminates scan- to-scan RNFL thickness measurement variation caused by manual placement of TD-OCT circle scan.
