A telemedicine data transfer system receives telemedicine data from a data source and decides whether to transmit the telemedicine data to a remote end circuit or prevent transmission of the telemedicine data to the remote end circuit based on a result of an evaluation. A telemedicine data transfer system includes image compression and decompression circuits. The decompression circuit may produce decompressed and enhanced telemedicine data. The image compression and decompression circuits include neural networks trained using an objective function to evaluate a difference between a training input data provided to the image compression circuit and a training output data that is output from the image decompression circuit. The training output data is made different from the training input data by a data enhancement operation performed on the training output data prior to the evaluation.

A method used for supporting ophthalmic examinations includes the step of preparing association information between medical information items and ophthalmic examination conditions. Patient information of a patient is transmitted from a client to a server configured to store and manage medical information. The server retrieves medical information of the patient based on the transmitted patient information, acquires a condition corresponding to the retrieved medical information from the association information, and transmits the acquired condition to the client. The client acquires examination data from the patient's eye based on the transmitted condition, and transmits the examination data together with the patient's patient information to the server. The server stores the transmitted examination data and/or an analysis result thereof. The server updates the association information by executing statistical processing on a medical information collection including examination data and/or analysis results of a plurality of patients.

An optical coherence tomography (OCT) image composed of a plurality of A-scans of a structure is analyzed by defining, for each A-scan, a set of neighboring A-scans surrounding the A-slices scan. Following an optional de-noising step, the neighboring A-scans are aligned in the imaging direction, then a matrix X is formed from the aligned A-scans, and matrix completion is performed to obtain a reduced speckle noise image.

A reference signal having a known induced optical delay is used for phase stabilization of optical coherence tomography (OCT) interferograms, and for correcting sampling differences within OCT interferograms, in single mode and multimodal OCT systems. The reference signal can then be used to the measure time shift or sample clock period shifts induced in the interferogram signal by the OCT system. A corresponding OCT interferogram signal can then be corrected to remove the shift induced by the system based on the determination.
A fundus analysis apparatus includes a storage, an area setting unit, and a morphological information generating unit.

Methods and apparatus for phase stabilized swept-source optical coherence tomography (SS-OCT) including rescaling and dynamic range enhancement
An optical coherence tomography (OCT) system electrically mixes a signature signal with an OCT signal (e.g., an interferogram) output by a photodetector of the OCT system. The signature signal may be a signal output by a photodetector that detects an optical signal from a fiber Bragg grating. The signature signal may then be time delayed before combination with the OCT signal. A series of interferograms are then aligned according to the signature signal. A rescaling signal may be similarly electrically mixed with the signature and OCT signals.

Abrégé
A method and system are proposed to obtain a reduced speckle noise image of a subject from optical coherence tomography (OCT) image data of the subject. The cross sectional images each comprise a plurality of scan lines obtained by measuring the time delay of light reflected, in a depth direction, from optical interfaces within the subject. The method comprises two aligning steps. First the cross sectional images are aligned, then image patches of the aligned cross sectional images are aligned to form a set of aligned patches. An image matrix is then formed from the aligned patches; and matrix completion is applied to the image matrix to obtain a reduced speckle noise image of the subject.
