Question

How can I add the new 10 MV Look Up Tables (LUT) to the myQA SRS device?

Answer

Please download and unzip the LUT for 10 MV and 10 MV FFF attached to this article.

Make sure to specify the Quality Index (QI) of your machine. The provided LUT were measured with QI = 0,7220 for 10 MV FFF and QI = 0,7410 for 10 MV FF. Please note: In case you use a different QI, the LUT will be interpolated.

Step 1

Open myQA Patients, connect to the myQA SRS device and connect with the Gantry Angle Sensor.

Step 2

Go to settings, select the energy you want to measure in the "Machine" Tab and go to the "calibration" tab. Click on "Apply gantry angle correction" and click on import. Select the LUT corresponding to your prior selected energy and click on open.

Note:

1. For 10 MV FFF, also an interpolated LUT will be shown. If the QI corresponds to the one defined in the LUT, the correct values will be used if you choose the LUT you uploaded. This will be fixed with the new myQA versions.

2. For 10 MV FFF, the term "FFF" is missing  in the "Energy/BQI" Tab. The correct FFF LUT will be used. This will also be fixed with the new myQA versions.
