Abstract: A multimodal imaging system and method is capable of taking fundus images, automatically identifying regions of interest (ROIs) of the eye from the fundus images, and performing OCT imaging in the identified ROIs, where the OCT images can provide clinically relevant information for screening purposes. By automatically identifying the ROIs, expert intervention is not required to perform specialized OCT imaging and thus, such imaging and analysis can be provided at more facilities and for more subjects for a lower cost.

Abstract: An ophthalmologic apparatus according to the embodiments includes an OCT optical system, an alignment unit, an image forming unit, a first calculator, and a second calculator. The OCT optical system is configured to acquire OCT data of a fundus of a subject's eye by projecting measurement light onto the fundus. The alignment unit is configured to perform alignment of the OCT optical system with reference to a predetermined site of the subject's eye. The image forming unit is configured to form a tomographic image of the fundus based on the OCT data acquired by the OCT optical system which has been aligned by the alignment unit. The first calculator is configured to calculate a first tilt angle of the tomographic image. The second calculator is configured to calculate a second tilt angle of the fundus by correcting the first tilt angle based on alignment result of the OCT optical system with respect to the predetermined site by the alignment unit.

Abstract: An ophthalmic apparatus includes an acquiring unit, an OCT unit, an analyzer, and a calculator. The acquiring unit is configured to acquire a dioptric power in a first region including a fovea of a subject's eye. The OCT unit is configured to acquire OCT data of a fundus of the subject's eye using optical coherence tomography. The analyzer is configured to specify a shape of the fundus by analyzing the OCT data. The calculator is configured to calculate a dioptric power in a peripheral region of the first region of the fundus based on the dioptric power in the first region and the shape of the fundus.

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. 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 each of a plurality of tomographic images acquired by the acquisition unit. The specifying unit is configured to obtain second shape data representing shape of the tissue based on the plurality of first shape data acquired by the tissue specifying unit.

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.
