Hi<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">I used Gate to simulate an ECAT system and I used the mac and root file to create .hs file by using Gatepet2STIR. But when I send file to virtual STIR and run a FBP reconstruction I get blank image. I used the example of Gate too and the
result was the same. would you help me to find the problem please.<br>
