The following fields are on the Users page:

Add User button

Click the Add User button ( ) to add users that can log into the LEADTOOLS Storage Server. Clicking the button adds a blank row to the User Accounts list view. The cursor moves to the User Name column in the new row so you can enter the new user's name.

Delete User button

• Permissions link

  Click the Permissions link beside the new user name to open the Edit Permissions dialog to select the permissions that the user will have. When finished, click OK to close the dialog and return to the Server Settings Dialog. The new user account will now be active.

Roles Page

The Roles page is shown in the following figure:

Use the Roles page to create new roles (groups of one or more permissions), and assign permissions to those roles. New or existing users can be assigned both permissions and roles.

The Roles page has the following fields: 

Role Drop-Down List

This list contains all existing roles.  By default, there is an Administrators role that contains all permissions. 

Add Role Button

To create a new role, click the Add Role button and enter the name for the role.

Delete Role Button

To remove a role, select the role in the role drop-down list and click the Delete Role button.

Permissions

This lists all permissions that can be assigned to a role. To assign a permission to a role, select the role in the role drop-down list, and select or clear the check boxes beside the appropriate permissions.

The CanChangeServerSettings permission does not include Patient Updater or image deletion privileges.

The CanDeleteFromDatabase permission grants deletions on a case-by-case basis (no mass deletions).

The CanEmptyDatabase permission grants deletion of the entire database. Only Administrators should have this permission, and should give themselves this permission only rarely.

The PatientUpdaterAdmin permission grants administration privileges for the Patient Updater (image and Patient Updater options alterations).

The PatientUpdaterDelete permission grants the privilege to delete images using the Patient Updater.

The PatientUpdaterEdit permission grants the privilege to edit images using the Patient Updater.

Database Manager Options Page

The Database Manager Options page is shown in the following figure: 

Use the Database Manager Options page to configure the behavior of the pagination control of the Database Manager, which is shown in the following figure:

 The Database Manager Options page has the following fields: 

Image Level Page Size

This is the maximum number of records displayed on a single page in the Database Manager.  When Display is Image Level, all pages except the last one will contain exactly the specified number of records. The last page will contain the remainder. If Display is Patient Level, Study Level, or Series Level, then the number of records in each page can be less than the Image Level Page Size.

Pagination Buttons Group

Use these options to specify when the Database Manager will display the pagination control.

(The pagination control is on the Database Manager tab and is shown in the following figure:

To navigate between pages, click the arrows or select a page number and click Go to Page.)

The Pagination Buttons group on the Database Manager Options page has the following radio buttons:

• Never Show

  Never display the pagination control.        

• Show When Necessary

  Display the pagination control only when necessary. For example, if the Image Level Page Size is 10 and there are 9 instances in the database, the pagination control would not be displayed because all instances fit on a single page.  However, if there were 11 instances in the database, the pagination control would be displayed because all instances do not fit on a single page.

• Always Show

  Always display the pagination control.  With this option the pagination control would be displayed if the Image Level Page Size is 10 and there are 9 instances in the database. 

As an example, suppose there are 25 total instances in your database.  If you set the ‘Image Level Page Size’ to 10, then clicking the Search button on the Database Manager will result in three pages of records.  The first and second pages each display ten records, and the last page displays five records.  Click the arrows or the Go to Page button to navigate between pages.

Anonymize Options Page

The Anonymize Options page is shown in the following figure: 

Use the Anonymize Options page to set up the anonymize scripts that can be used when exporting DICOM datasets from the Database Manager tab.

Anonymize Scripts Toolbar

At the top of the Anonymize Options page is an Anonymize Scripts toolbar, which has the following buttons:

• New Empty

  Creates a new, empty script (the script contains no tags).                

• New Default

  Creates a new, default script. A default script is a set list of commonly used tags and typical default values. Default values specify how tags will be anonymized. Refer to Anonymize Script Macros for a list of possible values.       

• Copy

  Makes a copy of the currently selected script. The new script's name is the same as the original, but with the word "Copy" appended to the name.

• Delete

  Deletes the selected script.               

• Activate

  Makes the selected script the active script. The active script is the script used when exporting DICOM datasets and has a green check mark beside it. The active script selection persists after the session ends and is the active script the next time the application opens.  The active script selection is used in the Export Selected dialog, as shown in the following figure:

Anonymize Scripts Listview

Below the Anonymize Scripts toolbar is the Anonymize Scripts listview, which lists the currently existing anonymize scripts. Initially, there is one script:

• Default 1

Note that initially on the Anonymize Options page the Default 1 script has a green check mark beside it.  The green check mark indicates that it is the active anonymize script.  The active anonymize script is the script selected in the Export Selected dialog. 

Any script can be made the active anonymize script simply by selecting it in the Anonymize Scripts list and clicking the Activate button on the Anonymize toolbar. 

Script Definition Group

The bottom panel of the Anonymize Options page is the Script Definition Group. Use it to insert or delete tags to compose the desired script.
