Abstract: According to a medical system of an aspect example, an ophthalmic data acquiring unit includes at least one ophthalmic examination apparatus for acquiring ophthalmic data from a patient, and an internal medicine data acquiring unit includes at least one internal medicine examination apparatus for acquiring internal medicine data from the patient. An inference processor is configured to perform inference processing using a trained model constructed by machine learning using training data that includes ophthalmic data, internal medicine data, and diagnostic result data. The inference processor generates inferred diagnostic data by performing the inference processing based at least on the ophthalmic data of the patient acquired by the ophthalmic data acquiring unit and the internal medicine data of the patient acquired by the internal medicine data acquiring unit. An output unit outputs a result of the inference processing performed by the inference processor.

Abstract: One aspect example is a system for photogrammetry of a building. A memory stores design data and physical material data. The design data includes virtual material information on attributes for each of virtual materials of a virtual building. The physical material data is on the attributes for each of physical materials and generated based on measured data acquired from a physical building constructed on the basis of the design data. A material associating processor is configured to generate pairs of virtual and physical materials by determining an association between the virtual materials and the physical materials based on the virtual material information and the physical material data. An attribute associating processor is configured to determine an association between the virtual material information and the physical material data in accordance with the attributes for each of the pairs.

Abstract: The object of the present invention is to develop an ophthalmologic microscope of a new method that increases the degree of freedom in the optical design in the Galilean ophthalmologic microscope provided with an OCT optical system. The present invention provides an ophthalmologic microscope, wherein an observation optical system, an objective lens, and an OCT optical system are placed in such a way that the optical axis of the OCT optical system does not penetrate through objective lens, and the optical axis of the observation optical system and the optical axis of the OCT optical system are non-coaxial, and wherein the ophthalmologic microscope further comprises a SLO optical system that scans a light ray which is a visible ray, a near infrared ray, or an infrared ray and guides the light to the subject's eye so as to become substantially coaxial with the optical axis of the OCT optical system.

Abstract: [Problem] An object of the present invention is to provide an ophthalmic microscope capable of observing, and acquiring a tomographic image of, an anterior ocular segment and a posterior ocular segment without changing a positional relationship between an objective lens and a subject eye.
Another object of the invention is to provide a function expansion unit capable of incorporating, into an ophthalmic microscope of existing specifications, a function capable of observing, and acquiring a tomographic image of, an anterior ocular segment and a posterior ocular segment without changing a positional relationship between an objective lens and a subject eye.
[Solution] There is provided an ophthalmic microscope including an observation optical system having a first focal point in front of a subject eye; an objective auxiliary lens capable of being set in a position on the subject eye side of an objective lens in the observation optical system or capable of being released from the position, a focal point at a time when the objective auxiliary lens is set being set to a second focal point which is an anterior ocular segment position of the subject eye; and a front lens capable of being set in a position further toward the subject eye side than the first focal point or capable of being released from the position, a focal point through the crystalline lens of the subject eye at a time when the front lens is set being set to a third focal point which is a posterior ocular segment position of the subject eye, the objective auxiliary lens being set and the front lens being released during anterior ocular segment observation, and the front lens being set and the objective auxiliary lens being released during posterior ocular segment observation, without changing a positional relationship between the objective lens and the subject eye.-

Abstract: An OCT apparatus of an exemplary aspect includes an OCT scanner, image data generating unit, registration unit, and image data composing unit. The OCT scanner is configured to acquire three dimensional data sets by applying an OCT scan to mutually different three dimensional regions of a sample. The image data generating unit is configured to generate a plurality of pieces of image data from the three dimensional data sets. The registration unit is configured to perform a first registration between the plurality of pieces of image data by applying an image correlation calculation to each of overlap regions in the plurality of pieces of image data. The image data composing unit is configured to compose the plurality of pieces of image data based on a result of the first registration.

Abstract: An ophthalmic apparatus of an exemplary aspect performs the first and second OCT scans on a subject's eye. The first OCT scan is performed on the first region including the first site of the subject's eye, and the second OCT scan is performed on the second region including the second site. The ophthalmic apparatus acquires the first deviation information of the subject's eye prior to the first OCT scan and performs alignment, and also acquires the second deviation information of the subject's eye prior to the second OCT scan and performs alignment. The ophthalmic apparatus calculates the distance between the first site and the second site based on the first data acquired through the first OCT scan and second data acquired through the second OCT scan.
