Abstract: An ophthalmologic information processing apparatus includes an acquisition unit, a tissue specifying unit, and a specifying unit. The acquisition unit is configured to acquire a tomographic image of a subject's eye formed based on scan data acquired using an optical system for performing optical coherence tomography on the subject's eye. The tissue specifying unit is configured to acquire first shape data representing shape of a tissue of the subject's eye by performing segmentation processing on the tomographic image. The specifying unit is configured to specify a low sensitivity component having a small variation with respect to a change in a position of the optical system with respect to the subject's eye from the first shape data, and to obtain second shape data representing shape of the tissue based on the specified low sensitivity component.

Abstract: The ophthalmic imaging apparatus of an embodiment example performs motion contrast imaging by applying OCT scanning to an eye. The data acquiring unit acquires a plurality of pieces of time-course data respectively corresponding to a plurality of scan points, by conducting repetitive A-scan application to individual scan points. The image constructing unit constructs a motion contrast image from the plurality of pieces of time-course data acquired. The controller controls the data acquiring unit such that data acquisition time intervals of first time-course data corresponding to a first scan point of the plurality of scan points and data acquisition time intervals of second time-course data corresponding to a second scan point become substantially equal to each other.

Abstract: The ophthalmic imaging apparatus (1) of an embodiment example performs motion contrast imaging by applying OCT scanning to an eye (E). The data acquiring unit (2, 100) acquires a plurality of pieces of time-course data respectively corresponding to a plurality of scan points, by conducting repetitive A-scan application to individual scan points. The image constructing unit (220) constructs a motion contrast image from the plurality of pieces of time-course data acquired. The controller (211) controls the data acquiring unit such that data acquisition time intervals of first time-course data corresponding to a first scan point of the plurality of scan points and data acquisition time intervals of second time-course data corresponding to a second scan point become substantially equal to each other.

Abstract: An exemplary OCT apparatus includes a scanner, controller, phase information generator, phase information processor. The scanner applies an OCT scan to an object using an optical scanner. The controller controls the scanner to perform a first scan that scans a cross section of the object in a first scan direction and a second scan that scans a cross section of the object in a second scan direction opposite to the first scan direction. The phase information generator generates first phase information based on first acquisition data acquired by the first scan and second phase information based on second acquisition data acquired by the second scan. The phase information processor generates composite phase information based on the first phase information and the second phase information.

Abstract: An ophthalmologic apparatus includes an SLO system, a projection system, a first image former, a second image former, a displacement processor, and a controller. The SLO system is configured to scan a target eye with first light deflected by an first optical scanner. The projection system is configured to project second light deflected by an second optical scanner onto the target eye. The first image former is configured to form a first image of the target eye based on a scan result of a first scan region using the first optical scanner. The second image former is configured to form a second image of the target eye based on a scan result of a second scan region using the first optical scanner, the second scan region being narrower than the first scan region. The displacement processor is configured to calculate a displacement between a partial image in the first image and the second image, the partial image corresponding to the second image. The controller is configured to control the second optical scanner based on the displacement.
