[Rtk-users] Problem while creating a phantom

[Vincent Libertiaux]

Hi RTK community,

I am getting unexpected results (see attached picture) when designing a 
phantom.

Here is my text file:

[Box]   A=70   B=15    C=4 z=0,    x=0,    y=0,    beta=0, gray=1
[Cylinder] A=0.8    B=15     C=0.8 z=0,    x=0,    y=0, beta=0,     gray=10

And the command I use for drawing:

rtkdrawgeometricphantom -o phantom.mha --phantomfile test.txt --spacing 
0.139 --dimension 1000

I am expecting a cylinder across my box, but as you can see on the 
attachment, the cylinder's radius decreases along its axis.

Could someone please give me a clue on what I am doing wrong ?

Many thanks,

Vincent
