<p>Hello Reza,</p>
<p>Please see section 6.1 of the general documentation pdf to have a
description of the mandatory/optional fields for the PET header
and binary datafiles. The position of the line of response in your
one coincidence example will be defined by the crystal ID1 and ID2
fields, which will be associated to the crystal ID look-up-table
as created for your scanner.<br>
</p>
<p>Additionally, you can have a look at the datafiles provided in
the benchmarks distributed on the website, or the <i>castor-datafileConversionEx
</i>script in the toolkits directory, which provides indications
regarding how to implement some script to generate a PET CASToR
datafile from any system datafile.</p>
<p>Regards,</p>
<p>Thibaut<br>

<div dir="ltr">Hello Castor Users,
<div><br>
</div>
<div>I was wondering if someone could explain how one can form a
binary datafile for a PET scanner. Let's assume an extensively
simple case in which I have a simple single-ring PET scanner
which recorded only one coincidence between crystals number 10
and 200 at time t=1 s. The scanner has already defined
properly and a crystal look-up table has been created for this
scanner. Now, I want to create a binary datafile for the one
recorded coincidence without any info on attenuation, scatter
or random correction.</div>
<div>How can this coincidence in the mentioned PET scanner be
defined using little endian encoding? Can somebody please walk
me through the steps?</div>
<div><br>
</div>
<div>Thank you for your help in advance!</div>
<div><br>
</div>
<div>Cheers,</div>
<div>Reza</div>
