A browser-based online annotation tool for 3D medical image volumes that allow annotations to be shared between users. The sharing feature allows images to be viewed across multiple users concurrently, and can sync viewing perspectives and drawings. For a shared viewing experience, changes made to a volume/image are updated automatically when a drawing is finished or a slice is changed.
The software utilizes Pusher, which eliminates the need for a server to handle real-time functionality.
The software contains 3 types of synchronization features for easy collaboration:
- Drag and drop the supported image from your local drive into the website
- Works with .drawing.nvd file saved after annotating
- Upload file through URL
- Parameter 'data' takes a URL of the supported image
- A default image is loaded if no file is found in the URL
- Type '?data=' after the URL from our website, then paste the link of a medical file
