<b>Subject:</b> [Gate-users] The design of CylindricalPET system with Rsectors
of different structures<o:p></o:p></span></p>
</div>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Dear users:<br>
I want to design a cylindrical PET system with four
Rsectors .In this system,the Rsectors have<br>
different structures.The number of modules of theirs is not equal.I have
tried a few ways to do that ,<br>
but all failed.Can someone tell me how to do that? <br>
<br>
Thank you very much!<br>
Best wishes! <o:p></o:p></p>
