OT-DICE Manual

6. Sample Sessions

Four sample sessions are provided below with each describing the test scenario, the steps taken to perform the test and the expected results.

6.1 Sample Session 1

Test Scenario

Send an image using DICOM C-STORE service demonstrating the usage of Storage SCU and Storage SCP services. Here we try to send the images to the same machine. A single instance of OT-DICE application is launched and the Storage SCP service is started. Switching to Storage SCU mode, we select the files, the Storage SCU initiates a request, gets a response from the SCP and then sends the images.

Steps

From the File menu select New Session. A new session named Untitled.ses will be created. In this session we will demonstrate the usage of Storage SCP and Storage SCU services.

  1. Switch to Storage SCP mode by either clicking on the STORAGE SCP button in the Mode window on the main window or by selecting Storage SCP from the Modes menu.

  2. Click on CONFIGURE NODES button or select Nodes from the Configure menu to bring up the Storage SCP Node Details dialog box.

  3. For our sample session enter the following values:

In the General page: 

AE Title

storescp

Port Number

104

Maximum PDU Size

16384

Write Transfer Syntax

Select ANY_TRANSFER_SYNTAX

Images Destination Folder

Click on the Browse button represented by the symbol … next to the Edit box. Select the folder in which you want the images to be stored or type in a folder name in the Edit box. If the folder does not exist, it will be created. For this session type something like:  C:\imagesreceived

In the Image Types page:

For this sample session click on the Check All check box. Checking the Check All check box ensures that the Storage SCP provides storage for all the image types available in the list.    

In the Transfer Syntax page:

For this sample session click on the Check All check box. Checking Check All check box ensures that the Storage SCP supports all three types of transfer syntaxes (LITTLE_ENDIAN_EXPLICIT_VR, LITTLE_ENDIAN_IMPLICIT_VR, BIG_ENDIAN_IMPLICIT_VR).    

  1. Click on the START button to start the storage SCP service. Now the Storage SCP service will listen in the specified port for any incoming associations.

  2. Switch to Storage SCU mode by either clicking on the STORAGE SCU button in the Mode window on the main window or by selecting Storage SCU from the Modes menu.

  3. Click on CONFIGURE NODES button and click on the ADD button to bring up the DICOM Node Details dialog box to create a node.

In the General page, enter the following values: 

Node Name

test_node

AE Title

storescp

Port Number

104

Maximum PDU Size

16384

IP Address

Give the IP address of your system or give localhost as the value if you are sending to the same machine. In this sample session, since we are sending to the same machine, you can specify either one of them.

Response Timeout

1000

In the Transfer Syntax page:

For this sample session click on the Check All check box. Checking the Check All check box ensures that the Storage SCU supports all three types of transfer syntaxes (LITTLE_ENDIAN_EXPLICIT_VR, LITTLE_ENDIAN_IMPLICIT_VR, BIG_ENDIAN_IMPLICIT_VR). Select the node created and click on the OK button.   

  1. The storescp value will appear in the Called AE Title combo box in the main window.

  5. Finally, click on the SEND button, which will transfer the images to the images received folder specified in the storage SCP Node Details Configuration dialog box.

  • The Remote Result window of Storage SCU will display the information sent by the remote node.

  • The Local Result window of the Storage SCP will display the information sent to the requesting node.

  • The Remote Result window of the Storage SCP will display the information sent by the requesting node.
