[Gate-users] voxelized phantom&source/different att map & activity map

[Anne Sauve]

> Hello the collaboration,
> 
> I am trying to implement the moby phantom into gate.
> I think I understand how to give gate an attenuation map as an 
> interfile.How to use att_range.dat and the act_range.dat.
> My understanding is that you have in your examples only one image 
> that represents
> both the voxelized phantom and source.
> My problem is that the Moby phantom has 2 images, one for attenuation
> and one for activity and they are different enough.
> I see a way (difficult though) to merge the 2 images into one and 
> segment it with respect to attenuation
> to fill att_range.dat and with respect with activity to fill 
> act_range.dat.
> Do you see an other way to do that ?
