<div>Nothing really strange to me.</div>
<div><br>
</div>
<div>Seeing your image with the air phantom, I think that your reconstruction setup is fine.</div>
<div><br>
</div>
<div>So it looks like the effect of attenuation correction that is not applied during reconstruction.<br>
</div>
<div><br>
</div>
<div>Try to correct for it and see.</div>

Hi,Simom</p>
<p style="word-wrap:break-word; margin-right:0px; margin-left:0px; font-size:13px">
I'm sorry about that. Here are some image pictures in attachments.</p>
<p style="word-wrap:break-word; margin-right:0px; margin-left:0px; font-size:13px">
At first, i thoutht that maybe scatter events were terrible, so i chose True evnets for GATE .root file, and with option "-isrc xxxx" in GATERootToCastor excutable to get the source image of simu, there was not so bad as recons. </p>

<div><font size="4" face="Times New Roman">Hi, Dear Castor users,</font>
<div><font size="4" face="Times New Roman"><span style="white-space:pre"></span> i met a confusion about CASTOR results.</font></div>
<div><font size="4" face="Times New Roman"> i created two GATE simulations, with phantom and several different radioactive sources, the difference is the material of phantom , one is air (little attenuation and scatter) and the other one is water,
(as described in attachment .mac files ). I chose TRUE events both from these two simulations separately, but what was surprised after CASToR recon was that, only the air phantom recon image was right , and the water phantom's was so strange. i checked
the true events, and did not find anything weird, so i did not know the reason , is there something wrong?</font></div>
