Ophthalmology OCT system and ophthalmology OCT imaging method

Abstract

An ophthalmic optical coherence tomography (OCT) system includes an OCT imaging system for a posterior segment of an eye and an OCT imaging system for an anterior segment of an eye. The OCT imaging system for the posterior segment of the eye includes a light path conversion device, and the OCT imaging system for the anterior segment of the eye includes a probe imaging device for the anterior segment of the eye. The probe imaging device for the anterior segment of the eye includes an ophthalmoscope, a first dichroscope and a first lens. When the ophthalmic OCT system is scanning image for the anterior segment of the eye, and after the light path conversion instruction is received by the light path conversion device, the signal light sent from the light source through the collimating mirror and scanning device respectively is converted into the probe imaging device for the anterior segment of the eye; the probe imaging device for the anterior segment of the eye drives the first dichroscope to cause the signal light to be reflected into the ophthalmoscope so as to carry out the scan imaging for the anterior segment of the eye. An ophthalmic OCT imaging method is used to image the anterior segment of the eye, which can both remain the point of fixation clear during dioptric compensation and not influence the OCT imaging quality for the anterior segment of the eye.

Description

Technical field [0001] The invention relates to the field of optoelectronics, in particular to an ophthalmology OCT system and an ophthalmology OCT imaging method. Background technique [0002] Optical Coherence Tomography (OCT, Optical Coherence Tomography) is an emerging optical imaging technology. Compared with traditional clinical imaging methods, it has the advantages of high resolution, imaging speed, no radiation damage, moderate price, compact structure, etc. It is an important potential tool for basic medical research and clinical diagnostic applications. Currently, among a variety of ophthalmic equipment using optical instruments, OCT devices for ophthalmic examination and treatment have become indispensable ophthalmic equipment for the diagnosis of ophthalmic diseases. [0003] Patent document US2009 / 0168017A1 discloses an OCT device that realizes anterior segment imaging in posterior segment OCT system, such as figure 1 As shown, a lens 132 is inserted after the sample...
