## Retrieve Files from a Remote Node

The DICOM Network Services utility lets you retrieve selected DICOM data from a remote machine, and store the files in the directory you associated with the Storage SCP service. To retrieve data, complete the following steps:

1. Click on the Query Retrieve SCU tab of the DICOM Network Services utility if it is not already selected.
2. Perform a query against a remote database. See Query the Remote Node for instructions.
3. In the Destination Node droplist, select the Application Entity name associated with the current Storage SCP service. If there is more than one Application Entity that supports Storage SCP, you can locate the name of the current entity on the Configuration tab in the grayed out Storage SCP Application Entity area.

4. In the Navigation Tree portion of the Results area, select the patient, study, series or image that you want to retrieve.

   Note: If you have selected Study Root in the Query Model area of the Query Fields dialog (described in Build or Modify a Custom Query), you cannot retrieve data at a patient level. You will need to select a study, series or image in the Navigation Tree.

5. Click Retrieve to return the selected data. This retrieves all images associated with a selected patient, study or series, or retrieves the selected image. Files are stored in the directory you associated with the Storage SCP Application Entity. The directory location is shown in the grayed out Storage SCP Application Entity area on the Configuration tab. Retrieve status information is available in the Status window.

There is a `Depot` subdirectory located in the directory you specified when configuring the Storage SCP Application Entity. This directory is used in the process of file retrieval and can be ignored. See About the Storage SCP Server for details.

Existing files with duplicate names are overwritten. See About the Storage SCP Service for details.

### Cancelling a Retrieval Operation

To halt the retrieval of data, click the Cancel button. This sends a cancel request to the remote node and halts file transfers.
