Abstract

The invention relates to the technical field of fundus optical coherence tomography imaging, in particular to a head-mounted OCT probe. The probe comprises a head-mounted shell which comprises a testposition corresponding to the eyes of a tested user; an imaging shell provided with an imaging light path corresponding to the test position; and an adjusting assembly used for movably installing theimaging shell in a wearable shell so that the relative positions of the imaging light path and the test position can be adjusted. According to the technical scheme, the imaging light path in the imaging shell is combined with the head-mounted shell; therefore, a light path system and the tested user can be kept in a relatively static state and move along with shaking of the head of the tested user, and the problems that focusing is difficult, the images are difficult to obtain, motion artifacts exist and the like due to the fact that the head of the tested user shakes continuously in a conventional OCT device or a handheld OCT device are solved.

Description

technical field [0001] The invention relates to the technical field of fundus optical coherence tomography imaging, in particular to a head-mounted OCT probe. Background technique [0002] Optical coherence tomography (OCT) is a non-invasive imaging method that has been widely used in the diagnosis and treatment of ophthalmic diseases in recent years, such as retinal vascular diseases, glaucoma, diabetic retinopathy and other ophthalmic diseases. [0003] At present, most commercial ophthalmic OCT devices on the market are bulky, complex, and costly. The data collection process is greatly affected by factors such as the external environment and the degree of patient cooperation, and requires a complex fixed focusing mechanism. For infants and young children It is particularly limited for data collection of special populations such as premature infants with retinopathy, bedridden patients, anesthetized patients, and patients who cannot maintain the required posture and fixati...
