How Do I Perform General Workflows for the myQA Machines Sphinx Plugin?

Create a Sphinx Protocol Template

• In the Test Setup workspace, select your machine and click Edit in the ribbon.
• Click New in the ribbon and enter the name of the protocol template.
• Click New and enter the name of the task template.
• Click New and enter the name of the test template And then select Other in Category; Sphinx in Result Type
• Click Import *.PLD, browse for, select, and open the PLD file.
• In the Geometry group, edit the values according to the actual setup if necessary.
• Defining the test: for the Output and Couch Translation categories:

See below an example of the procedure for defining an Output test.

• Under Analysis, click the Output tab and then select Create New.
• Enter a name
• Enter the expected value and tolerance.

For the Energy, Homogeneity, Spot, and Coincidence categories:

See an example of the procedure for defining an Energy test:

• Select an energy by clicking the corresponding button.
• Under Analysis, click the Energy tab and then select Create New and define the OOI.
• Edit the name of the OOI (Object of Interest).
• Select a value of the used wedge in the dropdown list:
• Wedge Thickness: Thickness of the wedge used for the selected energy if Sphinx Compact is used. For the Sphinx V1, it is always 20 mm / 65 mm.
• Additional Thickness: It is only used with Sphinx V1.
• Enter expected values and tolerances in the table.
• Enter the measurement settings, start a measurement by clicking the Start button, and then check whether in image fits to the defined OOI; if not, the Rotation or Shift in the Geometry group may need to be adjusted.
• Repeat the above steps to define a test for another energy until all the desired energy tests are defined.
• Click OK.
• Click Set Active to activate the protocol for test run.

Creating a Machine Protocol

• In the Machine & Template panel, select the machine to be tested.
• Click From Template in the ribbon and then select the protocol template created above.
• Check the parameters for all tests. Edit them if necessary,
• While the protocol is selected, click Set Active in the ribbon.
• Click Save in the ribbon.

Performing daily PBS QA

Workflow 1: Performing measurement manually and analysis

1. In Agenda, select the machine under Machines and task in the Active Tasks
2. Under Measurement Devices, select the detector. Under Settings, click  to connect, enter the measurement time and iris aperture (Sphinx V1) / gain (Sphinx Compact), and click  to measure the background.
3. Click to start measurements. After measurement finishes, analysis for the test categories, Energy, Homogeneity, Spot, and Coincidence, are automatically executed.
4. Analysis for Output: click the Output tab, and then select the test and enter the output values measured with PPC05.
5. Analysis for Couch Translation: click the Couch Translation tab, and then select the test and enter the actual values from the X-ray image analysis.
6. Click the Save Lynx Image button to save the image in DICOM format if desired.
7. Click the Finish button in the dialog and the Finish button ribbon.

Workflow 2: Loading an image for Analysis

1. In Agenda, select the machine under Machines and task in the Active Tasks
2. Click the Load Image Manually button and load the DICOM image.
3. Click . Analysis for test categories, Energy, Homogeneity, Spot, and Coincidence, will be executed.
4. Analysis for Output: click the Output tab, and then select the test and enter the output values measured with PPC05.
5. Analysis for Couch Translation: click the Couch Translation tab, and then select the test and enter the actual values from the X-ray image analysis.

Workflow 3: Performing Automatic measurement and analysis

Note: this workflow is only for the IBA PT users with Proton Therapy System (PTS) version R11 and the communication between the Sphinx Plugin and the PTS must be established.

1. In Test Run, select the machine under Machines and task in the Active Tasks
2. Under Measurement Devices, select the detector. Under Settings, Click to connect, enter the measurement time and iris aperture (Sphinx V1) / gain (Sphinx Compact), and click  to measure the background.
3. Analysis for Energy, Homogeneity, Spot, Coincidence, and Couch Translation: click .
4. Analysis for Output: click the Output tab, and then select the test and enter the output values measured with PPC05
5. Click the Save Lynx Image button to save the image in DICOM format if desired.
6. Click the Finish button in the dialog and the Finish button ribbon.

Setting up the PTS Communication

• Open the file, IBADos.CSP.Run.Shell.exe.config, in C:\Program Files (x86)\IBA Dosimetry\myQA with a text editor, e.g., Notepad, and move down to the line, “<add key="MQA_DOPA_Hostname" value="" />”
• Insert the address and the port of the PTS server inside the double quotation marks after “value=”, i.e., “<add key="MQA_DOPA_Hostname" value="xx.xxx.xxx.x:xxxx" />”.

Example 1 – single PTS address: e.g., value=”10.192.254.8:8082”

Example 2 – multiple PTS addresses: e.g., value="Room1=10.192.254.8:8082; Room2=10.192.254.0:8082" if the IP addresses of two treatment rooms need to be inserted.
