[Gate-users] Fan-beam x-ray source in Gate5.0.0

[baolin mao]

Dear Gaters:

In cone-beam CT simulation，I found the large photon number will cost so much
time in Gate5.0.0. Because I just need  five or six slice projection in the
middle of detection. I want to reduce the range of cone-beam source in the X
direction.

If you know how to set such x-ray source or the fan-beam source, please tell
me.
Thanks!
Yours Temmy
