Main PACS Server Demo Worklist AddIn

This add-in implements Service Class Provider (SCP) role of Modality Worklist Service (MWL) and corresponding Modality Performed Procedure Step (MPPS) service.

Database Editor Menus:

• Exit Menu - Closes the Database Editor Window

• Worklist Add-ins Options - Will display the following dialog:

  

  Worklist Configuration Dialog has the following options:

  • Modality Worklist C-Find Add-in PaneThese settings provide options for additional automatic filtering of query matching, attribute validation of client request and option to customize query matching keys and returned keys via XML script.

    
    Automatically restrict matching to schedule station AE title to client AE title.
    
    Auto exclude worklist items with checked (i.e. Completed, In progress etc) status.

  • Request Dataset Validation Pane This allows additional data validation on the query request for better system integrity.

    
    • Allow Zero Item Check Box - This will treat a sequence element with no child item element (i.e. FFFE, E000) in C-FIND Request attribute list from a client and will perform universal matching.
    • Allow Multiple Items Check Box - This will ignore additional Item elements (FFFE, E000) and will use the attribute values under the first item for query matching.
    • Allow Private Element Check Box - This will accept private elements in the query request attribute list from clients.
    • Allow Extra Elements Check Box - This will accept extra elements that are not listed under PS3.3 section K.6.1 of the DICOM standard.
    • IOD XML Path - Custom XML Script location on disk. Allows user to customize query matching keys and return keys via this script.

  • Modality Performed Procedure Step N-Create Add-in Pane

    This pane allows the options for data validation to maintain system integrity and option to map DICOM tag attribute value to database fields via XML script.

    

    Validate Relational Attribute According to the IHE Rules Check Box - When checked, this will validate simple/group cases and the patient and study information in MPPS against corresponding Modality Worklist.

    Allow Private Elements In Request Dataset Check Box - This will accept private elements in N-CREATE request. Add-in can only store the private attribute values to database if the data fields exist in the database and mapping is predefined via the XML script; otherwise it will ignore the private tag.

    Allow Extra Elements in The Request Dataset - This will accept additional DICOM defined elements (i.e. not listed in DICOM Standard PS3.4 Table F.7.2-1) in N-CREATE request. Add-in can only store the private attribute values to database if the data fields exist in the database and mapping is predefined via the XML script; otherwise it will ignore the extra tags.

    IOD XML Path - This allows user to predefine and customize the mapping of DICOM Attribute values to database fields; enabling add-in to store the values it receives from client via extra elements and private elements to database.

    Note: The user should extend (inherit) the Worklist DAL to update the new values and add the database fields before defining them in the XML script.

• Modality Performed Procedure Step N-Set Add-in Pane

  Data Manipulation View Pane:

  User can use this pane to manipulate (i.e. view, edit, add and delete) data stored in the worklist database. Refer to Query Pane for more information on how to retrieve data from worklist database used by the add-ins.

  Following are the fields in the Data Manipulation View:

  • Data-View Datagrid

    This view is used to display hierarchal data from the Worklist database; it also used for performing following operations:

    • Updating existent data.
    • Inserting new records
    • Deleting records.

    • Navigation through tables.

      

    The user can directly update existent data contained in the Data-View Datagrid which could be retrieved using the search option in Query Pane or can use the last empty record in the Data-View Datagrid to insert new records. While updating or inserting data, the user input will be validated to ensure its validity according to the following:

    Database conditions and constraints like primary and foreign keys.DICOM Rules like VR values and allowable values. User can also delete existent data by selecting a record(s) from the datagrid and using Delete Button. Up-Down navigation: is used to navigate from parent tables to child tables.

    Click on the plus sign displayed in the left of each record (

    
    ) to show a list that contains all the related child tables (), clicking on any table from the list will directly display all the child records related to the parent record. The parent's record will be displayed in the datagrid header
    

    Down-Up navigation: Commit Button: Undo changes button: Query Pane: Query For Drop-down List:Query Type Drop-down list:All records: Filtered records: Records related to Data-View selected entries:

Query Tabs
