[Gate-users] How to make an elliptical cylinder phantom？

[John Apostolakis]

Dear masa,

The ‘Elliptical Tube’ in Geant4 is NOT hollow.

It seems fairly clear from table 2.2 in section 2 of the documentation that the one in GATE similarly is also not hollow, as it is defined by 3 parameters: “setLong”, “setShort” and “setHeight”.

Best regards,
John

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!
masa
