<p>Hi Gabriel,</p>
<p><br>
</p>
<p>Indeed, it is not implemented has it requires a sinogram representation of the data with invariant sinogram bin size.</p>
<p><br>
</p>
<p>In some future, there will be a "sinogram scanner" in CASToR so that any type of PET, SPECT or CT data from a real scanner could be rebinned into a user's specified sinogram representation.<br>
</p>
<p><br>
</p>
<p>For the moment, you will have to look somewhere else for FBP2D.</p>

<p>Best</p>

Dear CASToR users<br>
<br>
I have been using this platform some months with iterative algorithms. Nowadays, I am trying to reconstruct some small spherical sources with FBP2D algorithm. Is there any possibility to achieve this goal with CASToR? I read time ago that this algorithm is
not implemented, but just to be sure<br>
<br>
Regards<br>
