Analysis Software
• Completely renewed with the plug’n’PET dual• First version completed and tested• Produces planograms for 3D reconstruction • Image reconstruction software development is still in progress
Ongoing developmenttoward the final DAQ
Final DAQ system
• Can handle up to 9 vs. 9 modules. • High performance FPGA •FPGA based fully digital coincidence logic will be implemented• Still at the development stage

Possible expansion (9 vs. 9 modules)
This would allow about 2x in sensitivity wrt 4 vs. 4
