[Gate-users] Question in building crystal in the SPECT

[林威佐]

I built the discrete crystals in my SPECT system.
The discrete crystals size was 58x58(mm) matrix of 2x2x6(mm)
crystals with 0.2 mm interpixel spacing.
My source was setted a point source,but I saw a lot of point sources in my
projection.
I think its my discrete crystals didn't set something let my projection
appear the wrong. What should I do to connect discrete crystals together?
