AIM Display Markups from Different Users
For a given image in an imaging study that has more than one reader interpreting and creating AIM annotations, the workstation can display every annotation while allowing you to turn off markups from a selected group of readers. Figure 11 depicts an image with three markups from three readers. The markup from reader named qwe-3 was turned off.
