<p>Dear Niccolo,<br>
<br>
Sorry for the late answer. There were some issues in the
calculations of rsector angular position when using a small number
of rsectors in the files I sent you. I believe this is the main
cause for the issues observed in your image.<br>
</p>
<p>Regarding the transaxial min angle difference variable, it is
evaluated from the crystal orientations. Some of the artifacts in
the reconstructed image could actually come from incorrect float
comparison operations linked to this variable.<br>
</p>
I attached a corrected version which will hopefully solve your
errors.<br>
<br>
Best regards, and thanks for helping exposing these bugs ! <br>

<div>I'm still facing some issues using the castor version you
sent me: </div>
<div>I simulated with gate an uniform fdg filled cylinder and
the PET scanner I sent in my previous email. </div>
<div>I was able to reconstruct it using the following command </div>
<div><br>
</div>
<div>>> ./castor-recon -df
~/prova_nick/UniformCylinder_<wbr>CstrProj.Cdh -fout
test_UniformCylinder -it 5:1 </div>
<div><br>
</div>
<div> but the image (you find in attachment) has some problem
(see test_UniformCylinder_it5.png).<wbr> </div>
<div>I attached all the data I'm using to reconstruct this
image: </div>
<div><br>
</div>
<div>UniformCylinder_CstrProj.Cdf (you should be able to
download it from my google drive )</div>
<div>UniformCylinder_CstrProj.Cdh (in attachment to this email)<br>
</div>
<div>MyScanner.geom (the geometry file as produced by the castor
version you sent me) </div>
<div><br>
</div>
<div>I also wanted to ask you an explanation about the <i><b>"min
angle difference parameter"</b></i>: </div>
<div>is it evaluated using the crystal orientation or using the
vector connecting the center of the crystal with the center
of the FOV?</div>
<div><br>
</div>
<div>Best regards and thank for your support</div>
