<p>What method are you talking about, the normalization, the optimization algorithm, or other ?</p>
<p><br>
</p>
<p>Yes it can as soon as you have at least 180 degrees of data, otherwise you will need to include prior knowledge into the reconstruction.</p>

<div>Thanks for the reply.</div>

<div>Do you mean that the method that reconstructs a full cylinder scanner image can also be used for a partial scanner?</div>

<p>Hi,</p>
<p><br>
</p>
<p>In terms of reconstructing images from tomographic data, CASToR can do whatever you tell it to do.</p>
<p>There is not limit, you can even design a "two crystals" PET scanner.</p>
<p>The use of look-up-tables is detailed in the documentation.<br>
</p>
<p><br>
</p>
<p>The limit for partial PET scanners is physical and not methodological.</p>
