Abstract

The invention relates to a human eye phantom for eyeground tomography and an OCT imaging quality evaluation method. The human eye phantom comprises a front refraction device and a rear refraction device; the front refraction device is used for collecting light and conducting imaging on the bottom surface of the rear refraction device, and the bottom surface of the rear refraction device is an arcsurface formed by concentric circles with different radiuses; the outer surface of the arc surface is covered with a retina resolution detection structure, and the retina resolution detection structure is further provided with a macular detection structure and an optic nerve detection structure.

Description

technical field [0001] The invention relates to a human eye phantom used for fundus tomography imaging and a method for evaluating OCT imaging quality. Background technique [0002] Optical coherence tomography (OCT) is an imaging technique developed rapidly in recent years. It uses the basic principle of weak coherent light interferometer to measure the back reflection or several scattered signals of incident weak coherent light at different depths of biological tissue, and then scan to obtain two-dimensional or three-dimensional structural images of biological tissue. [0003] At present, OCT is widely used in the fields of ophthalmology, neurology, and arterial interventional therapy, especially in the field of ophthalmology. It can be used for the diagnosis of macular diseases, the diagnosis of choroidal neovascularization diseases, the diagnosis of retinal diseases, the detection of ophthalmic diseases after surgery, and the detection of retinal nerve fibers. Quantitat...
