Customize Overlay Annotations in OmegaAI
Overview
OmegaAI provides a sophisticated feature that allows users to customize overlay annotations on images. This guide will walk you through accessing and configuring overlay annotations to enhance your visualization needs. The overlay customization interface supports detailed adjustments to each side of an image viewport, along with options for font and color changes.
Accessing Overlay Customization Settings
-
Open More Options: Start by navigating to the 'More Options' menu within the OmegaAI software interface.
-
Display Settings: In the 'More Options' menu, select 'Display Settings'.
-
Overlay Customizations: Within the 'Display Settings', choose 'Overlay Customizations'. This will take you to the customization screen.
Customizing Viewport Sides
You can customize annotations on any of the eight sides of each viewport:
-
Top Left
-
Top
-
Top Right
-

-
Bottom Right
-
Bottom
-
Bottom Left
-

To customize, simply click on the area you wish to modify. Here you can:
-
Add free text.
-
Select from predefined annotations.
-
Delete existing annotations (if not required).
Minimal and Full Overlay Annotations
-
Automatic Adjustment: If the viewport size is smaller than 500 pixels, OmegaAI automatically switches to minimal overlays to ensure clarity and usability.
-
Toggle Option: You can toggle between minimal and full overlays using the switch located at the top left of the customization screen.
Font and Color Settings
-
Font Selection: Click on the farmer's name adjacent to 'System Font' at the top left of the screen to change the font.
-
Color Adjustment: Click on 'Color' to open a palette and select your preferred color for the annotations. The chosen color will be applied to all annotations across the viewports.
Using DICOM Tags
-
Tag Integration: By using the hashtag (#) in the annotation field, you can bring up a search menu to locate available DICOM tags.
-
Adding Tags: Enter the DICOM tag directly or search for it to add specific data points to your annotations. These tags might include patient study information or calculated data not typically available as DICOM data.
