[Gate-users] Noise in CT image

[Ayush Maheshwari]

Hey,

On running the following example simulation: "classic CT" located at
"gate_v7.0/examples/example_CT/classic".
The image file obtained is very noisy.
I want to know if there is any scaling done for the pixel index
values? I have changed the number of pixels to 500 x 500 from 100 x
100 and changed the phantom geometry to a Air cylinder with four
Aluminium Balls present at same radius and different height. Rest of
the code is same as given in the example.

Following is the image obtained. What can I do to improve the image quality?
