</style><pre>Hi GATE users.
I am masa.
I want to make a phantom of an elliptical cylinder.
How can I make an elliptical cylinder phantom in GATE?
The CYLINDER phantom doesn't seem to be an ellipse, the ELLIPSOID phantom is a sphere, and the ELLIPTICAL TUBE phantom has a hollow inside.
Is it better to make the ELLIPSOID phantom very long and cut the top and bottom?
Thank you!
