摘要: An illumination system of an ophthalmologic microscope system projects illumination light onto a patient's eye. A light receiving system guides returning light of the illumination light to an image sensor. A display controller controls a display device to display an image obtained by the image sensor. A magnification changing unit changes display magnification of the image. An interference optical system detects interference light generated from returning light of measurement light from the eye and reference light. An optical scanner is used to scan the eye with the measurement light. An OCT data generation unit processes a detection result of the interference light to generate data. A condition setting unit sets a projection condition of the measurement light in accordance with change in the display magnification. An OCT controller controls the interference optical system and/or the optical scanner based on the projection condition.

摘要: An ophthalmic examination support system of an embodiment includes a server and clients. The server includes a medical information storage apparatus that stores medical information on each patient, and a management apparatus that manages the medical information. Each of the clients can communicate with the management apparatus. The system includes an association information storage unit and an examination condition obtaining unit. The association information storage unit stores, in advance, association information in which association between predetermined medical information items and examination conditions of an ophthalmic examination is recorded. The examination condition obtaining unit receives medical information retrieved from the medical information storage apparatus by the management apparatus based on patient information transmitted from one of the clients, and obtains an examination condition corresponding to at least part of the received medical information from the association information. The client executes control based on the examination condition obtained.

摘要: An illumination system for projecting illumination light onto an eye. A left (right) light receiving system includes a left (right) objective lens and left (right) image sensor, and guides returning light of the illumination light to the left (right) image sensor via the left (right) objective lens. The objective optical axes of the left and right light receiving systems are disposed nonparallelly to each other. A projection system includes a projection system objective lens, and projects light onto the eye via the projection system objective lens. An optical scanner is used for scanning the eye with the light from the projection system. A deflection member is disposed near the objective optical axes, disposed in the optical path of the projection system between the optical scanner and the projection system objective lens, and deflects the optical path.

摘要: An ophthalmic image display device having, a display controller that displays a B mode image, a blood vessel enhanced image representing a same cross section as the B mode image, and one or more front images individually formed based on a three dimensional data set acquired by performing optical coherence tomography on a subject's eye in a predetermined layout. Further, the display controller displays a cross section position indicator that indicates a position of a cross section of the B mode image over at least one of the one or more front images. In addition, the display controller synchronously performs changing of a display position of the cross section position indicator and updating of a display of each of the B mode image and the blood vessel enhanced image in accordance with an operation for moving the cross section position indicator performed using an operation unit.

摘要: An ophthalmic apparatus capable of selectively performing a first imaging mode in which imaging of a subject's eye is performed in a first state where an attachment unit is not attached, and a second imaging mode in which imaging of the subject's eye is performed in a second state where the attachment unit is attached. The ophthalmic apparatus includes: an operation unit; an attachment state determination unit to determine whether or not the attachment unit is attached; a correspondence determination unit to determine whether or not the correspondence between the imaging mode designated by a use of the operation unit and an attachment state of the attachment unit obtained by the attachment state determination unit is appropriate; and a controller to perform control for prohibiting imaging in at least the designated imaging mode when the correspondence determination unit has determined that the correspondence is not appropriate.

摘要: A fundus imaging apparatus includes a scanning optical system, a control circuit, and an image forming unit. The scanning optical system scans a fundus of a subject's eye with light from a light source, and receives return light from the fundus by a light receiver. The control circuit controls the scanning optical system such that a scanning locus is formed by the light in the fundus. The image forming unit forms an image of the fundus based on a light receiving signal from the light receiver and a position of the scanning locus. The control circuit is capable of performing an alignment mode, in which the control circuit controls the scanning optical system to project an alignment indicator for aligning the scanning optical system with the subject's eye on the fundus based on the light from the light source.

摘要: 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.
