OPHTHALMIC IMAGING DEVICE AND OPHTHALMIC IMAGING PROGRAM

摘要

An ophthalmic imaging device that captures an image of a test eye, the device includes: an OCT optical system configured to acquire an OCT signal by scanning a tissue of the test eye with measurement light, the ophthalmic imaging device configured to execute: receiving a designation of a wide area which is wider than a unit area which is an acquisition unit for acquiring motion contrast data indicating a motion of the tissue; acquiring a plurality of OCT signals for the same position at different timing in each of a plurality of unit areas, the plurality of unit areas being positioned in the designated wide area and being not completely overlapped with each other; and acquiring the motion contrast data of each of the plurality of unit areas by processing the plurality of OCT signals acquired for the same position.

1. An ophthalmic imaging device that captures an image of a test eye, the device comprising:
an OCT optical system configured to acquire an OCT signal by scanning a tissue of the test eye with measurement light; a processor; and a memory storing computer readable instructions, when executed by the processor, causing the ophthalmic imaging device to execute:
a wide area receiving instruction of receiving a designation of a wide area which is wider than a unit area which is an acquisition unit for acquiring motion contrast data indicating a motion of the tissue;a unit OCT signal acquisition instruction of acquiring a plurality of OCT signals for the same position at different timing in each of a plurality of unit areas, the plurality of unit areas being positioned in the designated wide area and being not completely overlapped with each other; anda unit data acquisition instruction of acquiring the motion contrast data of each of the plurality of unit areas by processing the plurality of OCT signals acquired for the same position.
