*Hi all,*
*I'm trying to simulate minigammacamera and my problem is that it takes too
long time. I have 4 slices to do (37,5 s each) and i'm still on first one
(16h!). Root file is now ~240 MB.*
*Is there any way to make it faster? Maybe i add to many parameters or
something is too much in my simulation?*
*I have to get a spectrum, FWHM, spatial resolution, heterogeneity,
sensitivity and count rate events.*
*With low activity everything wokrs fast, but i have to use 2 mCi and here
are problems.*
*Here is my source:*
/gate/source/addSource GammaSource
