Anyone has the experience of using the FilmQA pro for Elements commission.
How to know the setting of the depth of coronal view when we export the dose fluence of Elements to FilmQA pro?
Because Elements only can export 3D dose fluence, and the FilmQA pro define the depth which is from the range of dose grid.
So making sure the depth of FilmQA pro that we need to choose is difficult.

In Elements, you can set a location to export a 2D dose plane in the "Patient Specific QA", MME (or Cranial SRS), and RT QA Elements. If you select a 3D view (A/C/S) as the the layout, you can line up the crosshairs such that they intersect with the coronal plane that you want exported. Once you have the crosshairs aligned with the proper plane, if you click "CTRL-Shift-C" it will create a 2D dose plane at that level. You will get a pop-up window to select the folder where you want the dose plane exported to. The File name will be prepopulated with the .txt filename that will be saved to whichever folder you select (you can manually change the file name at that point if you wish to). In FilmQA Pro, you have the option of adding a "Brainlab" import option (under the planning software import options) so that it will allow you to import the .txt file.
If you want to export other dose planes from Elements (ie. an axial or a sagital), you can follow a similar method of aligning the crosshairs to the plane that you want to export and then once aligned, click "CTRL-SHIFT_A/C/S" (select A for axial, C for coronal or S for sagital).
If you are exporting a plane to use for FilmQA analysis, you can visually see the plane in the CT of your phantom that you want to export and use that as a guide to align your crosshairs properly in order to export the correct dose plane.
For QA of very small targets, if you are an Eclipse user, I have found that exporting the dose plane from Eclipse can lend to better agreement with film measurements as you can export a dose plane with finer resolution from Eclipse than you can from Elements. A plane that has a 1mm dose grid can be too course for a target that is only 4-5mm in diameter and can lead to discrepancies in agreement with film that can be rectified with the export of a finer resolution dose plane.
UCLA - Drs. Agazaryan and Tenn,
We have used FilmQA Pro extensively for the Elements commissioning. However, we have not used the method specifically described. We have either exported a film plane from Elements using the method described below or exported the film plane from Eclipse after importing there first.
We think you can export a film plane if you click (Control- ?) the ‘?’ being replaced by C, A, S for coronal, axial or sagittal planes respectively that are being viewed at the time.
