Thanks Karthik,<br><br>I can get access to a Philips scanner but it is used in a clinical environment so Its every difficult to get time its workstation. I have looked at STIR but I don't believe STIR has profiles for Philips scanners nor does it implement the RAMLA algorithm. I am using a macro provided by F. Lamare as published in<br><br><h2 class="abstitle">Validation of a Monte Carlo simulation of the Philips Allegro/GEMINI PET systems using GATE</h2>

If you don't have a scanner with Philips reconstruction software, you could try STIR (
