Title: TOMOGRAPHIC IMAGE PROCESSING DEVICE, OPHTHALMIC DEVICE COMPRISING THE SAME AND NON-TRANSITORY COMPUTER-READABLE RECORDING MEDIUM STORING COMPUTER-READABLE INSTRUCTIONS FOR TOMOGRAPHIC IMAGE PROCESSING DEVICE
Abstract: [0001]    A tomographic image processing device may include: an input unit configured to input a tomographic image of a subject eye; a processor; and a memory storing computer-readable instructions therein. The computer-readable instructions, when executed by the processor, may cause the processor to execute: acquiring a tomographic image of a normal eye; acquiring a tomographic image of an eye having an abnormal portion; extracting a feature amount of the abnormal portion by using machine learning from the tomographic image of the normal eye and the tomographic image of the eye having the abnormal portion; acquiring a tomographic image of the subject eye inputted to the input unit; and determining whether the tomographic image of the subject eye includes an abnormal portion based on the feature amount.

Claims: number: 1
text: A tomographic image processing device (10) comprising:
number: 2
text: The tomographic image processing device (10) according to claim 1, further comprising a display unit (32) configured to display an image of the subject eye,
wherein when the display unit (32) displays the tomographic image of the subject eye in a case where it is determined that the tomographic image of the subject eye includes the abnormal portion, the display unit (32) is configured to be capable of displaying the abnormal portion and a portion where the abnormal portion does not exist in different manners.
number: 3
text: The tomographic image processing device (10) according to claim 1 or 2, wherein
the tomographic image of the subject eye comprises a first tomographic image and a second tomographic image, the first tomographic image being captured by irradiating the subject eye with a first polarized wave, the second tomographic image being captured by irradiating the subject eye with a second polarized wave that has a vibration direction different from the first polarized wave, and
the computer-readable instructions, when executed by the processor (12), further cause the processor (12) to execute:
calculating an entropy based on the first tomographic image and the second tomographic image for a same cross section of the subject eye.
number: 4
text: The tomographic image processing device (10) according to any one of claims 1 to 3, wherein
the computer-readable instructions, when executed by the processor (12), further cause the processor (12) to execute:
number: 5
text: The tomographic image processing device (10) according to claim 4, further comprising a display unit (32) configured to display an image of the subject eye,
wherein the display unit (32) is configured to display the image of the subject eye with a line that is drawn along the determined inter-tissue boundary superimposed over the image of the subject eye.
number: 6
text: An ophthalmic device (100) comprising:
number: 7
text: A non-transitory computer-readable recording medium storing computer-readable instructions for a tomographic image processing device (10),
wherein the computer-readable instructions, when executed by a processor (12) of the tomographic image processing device (10), cause the processor (12) to:
number: 8
text: The non-transitory computer-readable recording medium according to claim 7,
wherein the computer-readable instructions, when executed by a processor (12) of the tomographic image processing device (10), further cause the processor (12) to:
