<p>Hello,</p>
<p>As a user of CASToR, I have extensively use it for 2-head PET reconstruction for experimental and simulation data. But there are many parameters that could go wrong. It needs caution.</p>

<div>Hello </div>
<div> </div>
<div>We designed a partial PET scanner based on a cylinder PET scanner but we could not reconstruct the exact image. Is there a limit to the Castor application that cannot reconstruct a dual PET scanner?</div>
<div> </div>
<div>Thanks,</div>
