Abstract
Methods and systems for identifying CNV membranes and vasculature in images obtained using noninvasive imaging techniques are described. An example method includes generating, by a first model based on at least one image of a retina of a subject, a membrane mask indicating a location of a CNV membrane in the retina. The method further includes generating, by a second model based on the membrane mask and the at least one image, a vasculature mask of the retina of the subject, the vasculature mask indicating CNV vascularization in the retina.
Claims20
A medical device comprising:
- an imaging device configured to generate at least one image of a retina of a subject by performing a projection-resolved optical coherence tomographic angiography (PR-OCTA) scan on the retina of the subject;
- at least one processor;
- memory storing instructions that, when executed by the at least one processor, cause the at least one processor to perform operations comprising:
- generating, by a first model based on the at least one image of the retina of the subject, a membrane mask indicating a location of a choroidal neovascularization (CNV) membrane in the retina;
- determining that a size of the CNV membrane indicated in the membrane mask is greater than a threshold size;
- and
- generating, by a second model based on the membrane mask and the at least one image, a vasculature mask of the retina of the subject, the vasculature mask indicating CNV vascularization in the retina;
- and
- a display device configured to display at least one of the membrane mask or the vasculature mask.
A method, comprising:
- generating, by a first model based on at least one image of a retina of a subject, a membrane mask indicating a location of a a choroidal neovascularization (CNV) membrane in the retina;
- and
- generating, by a second model based on the membrane mask and the at least one image, a vasculature mask of the retina of the subject, the vasculature mask indicating CNV vascularization in the retina.
A system, comprising:
- at least one processor;
- and
- memory storing instructions that, when executed by the at least one processor, cause the at least one processor to perform:
- a first model configured to generate, based on at least one image of a retina of a subject, a membrane mask indicating a first location of a a choroidal neovascularization (CNV) membrane in the retina;
- and
- a second model configured to generate, based on the membrane mask and the at least one image, a vasculature mask of indicating a second location of at least one vessel in the CNV membrane.
