If you mean Digitally Reconstructed Radiograph (DRR), this is what is called forward projection in RTK. See e.g.<br>

<p>Hi Sam,</p>
<p><br>
</p>
<p>I think you need to ask a more precise question. RTK is primarily a tomography toolkit, but contains some pre-processing methods that might suit your needs.<br>
</p>
<p>Can you describe what you are trying to do ? <br>
