- ### Format drop-down list The file type of the thumbnail image. Possible values are as follows: - Jpeg - J2K - Tif - TifJpeg - TifJ2k

- - ### Generate Images group

- ### Add button Click Add to open an Image Format dialog that lets you specify the width, height, lossy or lossless Compression, Q Factor and file format. You can add as many thumbnail setting sets as you like. Each one creates a different thumbnail for each image stored with the specified settings.

- ### Edit button Select an item in the Generate Images list view and click **Edit** to open the Image Format dialog for that image format for modification.

- ### Delete button Select a set of settings in the Generate Images list view and click **Delete** to delete a thumbnail format from the specified set.

- ### Options Tab The Options tab allows you to specify options to be used when storing or updating images. Storage Server Storage Options Tab The following fields are on the Options tab:

- ### Prevent Storing Duplicate SOP Instance check box This will prevent the server from allowing a client to store, and therefore overwrite an image that has the same identifier. Only clients that have the update permission can do this, but selecting this option will prevent even these clients from overwriting.

- ### Update Options: group These options determine the behavior of the server when an image with a duplicate identifier is stored and that image has conflicting information. In most cases leave these options turned off.

- ### Update Existing Patient check box If the image with the duplicate identifier has different patient information (name, DOB, PID, Sex), turning this option on will allow the server to overwrite the existing information for all of the existing images for that patient in the database tables. The DICOM tags will be left unaffected.

- ### Update Existing Study check box If the image with the duplicate identifier has different study information (study type, date), turning this option on will allow the server to overwrite the existing information for this study in the database tables. The DICOM tags will be left unaffected.

- ### Update Existing Series check box If the image with the duplicate identifier has different series information (series date, series type), turning this option on will allow the server to overwrite the existing information for that series in the database tables. The DICOM tags will be left unaffected.

- ### Update Existing Instance check box If the image with the duplicate identifier has different instance information (instance date, instance type), turning this option on will allow the server to overwrite the existing information for that instance in the database tables. The DICOM tags will be left unaffected.

- ### Auto Truncate Data check box Automatically truncates any stored data to the maximum defined length by the DICOM specification. Note that enabling this option affects storage performance, so it should be used only if necessary.

- ### Requested Dataset Validation group This group of fields are used when validating incoming C-Find requests. These options allow you to be less restrictive than what is specified in the DICOM specification about incoming C-Find requests. Each option is described below.

- ### Allow zero items check box Select the check box to allow C-Find requests with sequences that contain no items.

- ### Allow multiple items check box Select the check box to allow C-Find requests with sequences that contain more than one item.

- ### Allow private elements check box Select the check box to allow C-Find requests that contain private DICOM elements.

- ### Allow extra elements check box Select the check box to allow the check box to allow queries to have extra elements.

- ### Response Dataset group This group allows you to specify what to include in responses. If a check box is selected, the selected item is included in the server's response to the client. On the client's side, if the client has a field to display that item in the client's query list, it will be displayed.

- ### Include Number of Patient-related Studies check box Select the check box to include the Patient-Related Studies element (0020,1200) in the C-Find Response

- ### Include Number of Patient-related Series check box Select the check box to include the Patient-Related Series element (0020,1202) in the C-Find Response.

- ### Include Number of Study Related Series check box Select the check box to include the Study-Related Series element (0020,1206) in the C-Find Response.

- ### Include Number of Study Related Instances check box Select the check box to include the Study Related Instances element (0020,1208) in the C-Find Response.

- ### Include Number of Series-Related Instances check box Select the check box to include the Series Related Instances (0020,1209) element in the C-Find Response.

- ### Response Count group This group allows you to prevent a DICOM client from slowing down the server by performing a blank query (for all records on server).

- ### Limit Number of CFind-Rsp Per Request check box Select the check box to limit the number of responses to a C-Find\_Req. If the check box is clear, then there is no limit to the number of responses. Use the numeric spin box beside the check box to enter the maximum number of responses (up to 999) that the server will return per C-Find-Req.

- ### Service Status for Final CFind-Rsp entry field and Attribute List Error drop-down list box . The DICOM specification defines the values in the Attribute List Error drop-down list box. Selecting one of these values causes the corresponding 4-digit hex value to appear in the Service Status for Final CFind-Rsp entry field.

- ### IOD XML Path entry field and Browse button The path of an XML file which describes the DICOM Query IOD supported by the C-Find command.
