[Gate-users] Rectangular shape of projection image for point source

[Khalid Hussain]

Dear Gate user,

I am getting a rectangular shaped projection image by simulating a point
source.
The image should be a point shaped like a small sphere not a rectangular.
The projection image is attached below

[image: image.png]

The script I used is given below;
/gate/source/addSource Point
/gate/source/Point/gps/type Point
/gate/source/Point/gps/centre 0. 0. 0. cm
/gate/source/Point/gps/particle gamma
/gate/source/Point/gps/energy  140.0 keV
/gate/source/Point/setActivity 3.7 MBq
/gate/source/Point/gps/angtype iso
/gate/source/Point/gps/mintheta 0. deg
/gate/source/Point/gps/maxtheta 180. deg
/gate/source/Point/gps/minphi 0. deg
/gate/source/Point/gps/maxphi 360. deg
/gate/source/Point/gps/direction 0. 0. 1.0

Please guid about the possible problem.

Thank you
