<p>Hi Reza,</p>
<p> </p>
<p>This is a good point but we did not have time yet to implement it. This feature will be provided in the next release.</p>

<div dir="ltr">Hello,
<div><br>
</div>
<div>When reconstructing PET list-mode data with attenuation correction, CASToR requires an attenuation correction factor for each event in the input *.cdf file. Also, if the attenuation correction flag is on, an attenuation image needs to be passed to CASToR
which, as far as I understand, is used during normalization. </div>
<div><br>
</div>
<div>I am wondering why CASToR doesn't use the input attenuation image to calculate an attenuation correction factor for each event automatically?</div>
<div><br>
</div>
<div>Thank you all,</div>
<div><br>
</div>
<div>Cheers,</div>
