摘要： An optical coherence tomography image system and an autofocus method thereof are provided. The autofocus method captures a reference chart at a plurality of preset diopter positions, receives an interference signal generated by the reflection of a light beam projected onto an eyeball, and analyzes the reference chart and the interference signal to obtain an analysis value and a corresponding diopter. The method compares the plurality of analysis values to obtain one meeting the standard condition as the target analysis value. According to the target analysis value and the corresponding diopter, the focusing driving device is controlled to move to the position corresponding to the diopter to complete autofocusing. Therefore, the present invention can reduce the time of autofocusing, obtain a higher shooting success rate, provide better user experience, and use a lower-order computing device to reduce costs.

摘要： The methods and systems provided can automatically determine an Arteriolar-to-Venular diameter Ratio, AVR, in blood vessels, such as retinal blood vessels and other blood vessels in vertebrates. The AVR is an important predictor of increases in the risk for stroke, cerebral atrophy, cognitive decline, and myocardial infarct.

摘要： The present invention describes systems and method for the detection, diagnosis and monitoring of cognitive impairment and Alzheimer's disease. In one example, an integrated system comprising a full-field Fourier domain optical coherence tomography and an image mapping spectrometry is used for generating spectrally resolved volumetric images at wavelengths that show difference in spectral signatures of normal cells compared to spectral signatures of amyloid beta and pTau deposits, and also image inner retinal layers where amyloid beta and pTau deposits may aggregate.

摘要： An ophthalmic device (1) of the present invention has an optical head (2) including a light projection optical system (21) that projects light onto a subject eye (E), a light reception optical system (22) that receives light from the subject eye (E), and a fixation lamp (23) for guiding a line-of-sight direction of the subject eye (E), and a turning drive unit that turns the optical head (2) in a horizontal direction while maintaining positional relationships between the light projection optical system (21), the light reception optical system (22), and the fixation lamp (23). The turning drive unit is composed of a rotational drive unit (4) that rotates the optical head (2) in the horizontal direction and a horizontal drive unit (3) that moves the optical head (2) in the horizontal direction.

摘要： An electronic device for predicting myopia regression, which includes a memory and a processor connected with the memory to execute instructions included in the memory. The processor collects first target data of a subject and second target data of the subject, extracts a first result value as output data for a first machine learning model by using the first target data as input data for the first machine learning model, and determines whether there is a possibility of myopia regression of the subject based on the first result value.

摘要： An image processing method includes acquiring a three-dimensional image of a subject eye and a two-dimensional image of the subject eye, specifying a first reference point in the three-dimensional image, specifying a second reference point in the two-dimensional image, and generating a superposed image. In the superposed image, the first reference point in the three-dimensional image is coordinated with the second reference point in the two-dimensional image and the two-dimensional image is superposed with at least a portion of the three-dimensional image.

摘要： The present invention discloses a system for an Intelligent Single Tool for Clinicians for detecting abnormalities in eyes, brain, heart and kidney of a patient. The method comprising a sequential procedure for capturing and processing the retinal image by an edge device, which has an IOT sensor embedded in it, and connected to a FOG device, which simply relays the image captured by edge device to the cloud. Processing on the retinal image take place at the FOG device, which can be a mobile or a desktop/laptop or a server that configured with the AI application that interfaces with edge device on one side and with cloud on the other end and sending the captured, processed, and evaluated retinal image to a cloud server for extensive processing. Further, the processing of the retinal image facilitates determining 6 eye related diseases, and deriving abnormalities at the heart, brain and kidneys.

摘要： A system including first and second camera assemblies, and a processor. The first camera assembly includes a first camera producing, in a first imaging modality, a first image of an organ acquired from a first angle, and a first position sensor, producing a first position signal indicative of a first position and a first orientation, of the first camera. The second camera assembly includes a second camera, producing, in a second imaging modality, a second image of the organ acquired from a second angle, and a second position sensor, producing a second position signal indicative of a second position and a second orientation, of the second camera. The processor registers between the first and second images based on the first and second position signals and displays, based on the first and second images, a third image including a combination of at least part of the first and second images.
