Elekta Las Vegas Phantom

I am trying to analyse the Las Vegas phantom: field size: 12x12, SSD: 100cm, 10MU

“Unable to find the phantom in the image. Potential solutions: check the SSD was passed correctly, check that the phantom isn’t at the edge of the field, check that the phantom is centered along the CAX.”

I think you have to increase the field size. According to the documentation restriction #1 is: The phantom must not be touching any image edges.


Yes thank you, the manual indicates 12x12, i had to set 15x15 so the phantom can be seen in the image.
