Question
How do I create a template in myQA Machines designed to verify the picket fence plan employed by Halcyon LINACs using both the Proximal and Distal MLC Leaf Banks?
Answer
In order to do this, go to myQA Machines and test set up. Go to your machine and template and either use one of the predefined MLC QA taks in the TG-142 + Plugin Template provided with myQA. Or you can use the add new item and create a MLC QA Task (see screenshot example below).
Step 1
Open the module of the task.
Step 2
Click MLC Model and edit. Advise using the Proximal Model as Varian provides a picket fence plan for either distal or the combination of the two MLC leaf banks.
Step 3
Click in the Leaves window and enter the appropriate number of leaves and width. The number of leaves is 57 and the width is 5.0 mm (a combination of overlapping 29 pairs and 28 pairs of the proximal and distal banks which each bank having a 10 mm width).
Step 4
Double-click on your model and you can rename it.
Step 5
Loaded in your dicom or .tiff file and perform your analysis. In some cases, you may need to crop the image if the analysis fails. This can be done currently with third-party software.
