[Gate-users] RE: Reconstruction for Philips Allegro

[Pranesh Raniga]

Thanks Karthik,

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

Validation of a Monte Carlo simulation of the Philips Allegro/GEMINI PET systems using GATE
F Lamare et al 2006 Phys. Med. Biol. 51 943-962   doi:10.1088/0031-9155/51/4/013I am not certain if deadtimes are included.

Cheers,
Parnesh

Pranesh,

  If you already have a Philips scanner, you could take the crystal and block IDs and create a listmode file that the Philips scanner understands. If you don't have a scanner with Philips reconstruction software, you could try STIR (
http://stir.sourceforge.net/main.htm).

   Do you have deadtimes included in your GATE macro? I would be interested in seeing your GATE marco file for the Allegro scanner.


Karthik
