Prior Studies

Previous pageReturn to chapter overviewNext page


Although it is a manual process, there are rules that can be configured to customize the search for (and reconciliation of) prior studies. However, it is not recommended that these rules be changed from their default values unless you are absolutely certain the changes you have made are correct and will not adversely impact patient care. Modifying these rules can result in incorrect priors being listed, or in true priors being missed altogether.

For more detailed information on how prior studies are found or reconciled, please consult the Workstation DICOM conformance statement, which is available on our website.

Once the study (or studies) you selected has opened, the Workstation will automatically search the local store and your priors servers for related/prior studies and load them into the viewer. The prior studies will gradually appear in the right-click context menu and thumbnail panel as they are loaded. In the screenshot below, the thumbnail panel and right-click menu show two different studies have been loaded, but only one study was actually selected to be opened.

Note that, in the case where you have selected a priors server that is not an installation of ClearCanvas ImageServer, the prior studies will appear in the viewer's context menu, but you will be unable to view them. Their presence in the context menu is simply to let you know that those prior studies exist. In order to view them, you must retrieve them to your local machine, close the viewer, and reopen the studies. This kind of workflow problem is usually solved by auto-routing relevant priors to the appropriate workstation(s). Your PACS administrator will be able to tell you what's possible with your current system.


In the event that one of your priors servers cannot be contacted, the software will warn you once (see adjacent dialog) that some prior studies may not be available and it will not warn you again until after the next time the server has been queried successfully. Please refer to the safety instructions for more information.
