How to save time time while performing nailfold capillaroscopy - A diagnostic tool
We believe that practice of capillaroscopy should be improved
Capillary.io turns observation into precise data. Every capillary and each region of the nailfold is analyzed automatically, generating clear, objective metrics that support an objective and reproducible assessment.
Save time without changing your workflow. Our algorithms detect, measure, and classify capillaries and hemorrhages and generate an automatic report. The CapillaryScope app guides image capture with your capillaroscope and organizes the images, which are instantly available in the web application.
Boost clinical adoption and research. Securely share your image database, collaborate with other professionals, and explore your data with full control. Capillary.io integrates into your organization to make capillaroscopy more productive.
