<p>Hello Adolf,</p>
<p>Yes, you could use the root data to reconstruct an image from the
simulated acquisition. There are several free softwares available
for image reconstruction if you don't have your own reconstruction
code. You could try to use <a href="http://castor-project.org/">CASToR</a>
which implements several tools to reconstruct SPECT datasets
simulated with GATE. You will first have to create a CASToR
datafile from the root output using the <i>castor-GATERootToCastor</i>
executable.<br>
</p>
I attached two example scripts for the conversion and reconstruction
of the GATE SPECT benchmark dataset. You can launch them from the
benchSPECT directory.<br>
<p>
Let me know if you have any questions.</p>
Best regards,<br>
Thibaut M.<br>
