Setting AIM Data Service Options
The purpose of AIM on the ClearCanvas workstation is to connect to multiple AIM Data Services that can accommodate the AIM 3.0 information model. As a result, these data services are collectively known as AIM 3.0 Data Services.
While by default the workstation is not configured to connect to any AIM 3.0 Data Services, it can use the AIM 3.0 Data Service. An end user can enter any valid URL for the AIM Data Service and click the Save button to have that URL remain on the workstation for future sessions.
Click 
to configure the AIM Data Service. You can access the data service configuration from the explorer toolbar, shown in (Fig 1), or through an opened study's toolbar, shown in (Fig 2).

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. (Fig 11) depicts an image with three markups from three readers. The markup from reader named qwe-3 was turned off.
A right-mouse click on the image activates a pop-up menu with a "Visible AIM Users" option to turn readers' markups on or off.

ByThis whole paragraph needs to be rewritten and structured as a procedure. Very unclear. default, the workstation also displays annotations created by different users in different colors. Selecting Tools -> Options -> AIM -> Markup allows you to change which colors are used for which user's AIM annotations (Fig 12). Selected by default, the "Random" checkbox (#2) assigns a random color to each user. If you do not select the option, you can override the random color with a different color. You can also override the color used to depict one or more user's AIM annotions. The default color may be changed by clicking the button to the left of the checkbox when the checkbox is deselected. A user's color may be changed by clicking the color next to their name and selecting a new color in the color picker dialog that appears. Users not yet loaded into the list may be added to the list by clicking the "Add Login" button (#3). Selected users may be removed from the list (resetting their colors to the default) by selecting the "Remove Selected" button (#4). All users in the list may be selected by clicking the "Select All" button (#5). Selected users may have their color reset to the default color, either random or predefined as determined by the Random checkbox (#2), by clicking the "Reset To Default Color" button (#6).
