SIMBA Advanced Image Viewer Operation:

 

Annotation Control Panel

 

The Annotation control panel, shown below, is displayed below the viewport image when the “Mark” button is clicked. See the SIMBA Advanced Image Viewer for image viewport information. This panel permits the control of editing one or more closed region boundaries (or multi-segment lines) on an image or on a set of images. These boundaries may be saved in a “bookmark”. The available bookmarks for an image are listed when the Annotations button is clicked

 

 

 

The buttons have the following functions:
