AIM Annotation Details

The AIM annotation details, as illustrated by Figure 11, allow a user to examine detailed information captured in an AIM instance. To access this feature, you select an image containing an AIM instance and then click the AIM Details button, as shown in (#1). The AIM Annotation Details panel appears. This panel contains information tabs including Anatomic Entity, Imaging Observation, Calculations, and All Details. The All Details tab (shown in #3) allows a user to see information related to both Anatomic Entity and Imaging Observation and their characteristics.

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 12 depicts an image with three markups from three readers. The markup from reader named qwe-3 was turned off.
