Field Analysis Elekta EPID

Hi All,

I have encountered ‘fwxm_data’ was not in the range: (0, 100). Any quick fix?

Setting invert=True did it for me.

fa = pylinac.FieldAnalysis(…)
fa.analyze(invert=True)

Hi James,

Yes, it’s working now. Thank you!

Is there a way to check or display the resolution of the image in mm per pixel?

The dpmm attribute. dpmm is dots/pixels per mm so 1/dpmm is mm/pixel

1/fa.image.dpmm
