<div dir="ltr">Dear Dr. Kang,<div><br></div><div>Thank you for your quick reply. The manual in your attachment is mainly for regular X-ray CT simulation without NCAT phantom implementation. What I am interested in is the application of NCAT phantom in CT simulation. Particularly I have the following questions:</div><div><br></div><div>1. Is NCAT phantom included in GATE? In other words, do I need to download any data files in order to use it?</div><div>2. How is the respiratory motion implemented with the phantom?</div><div>3. I know Duke Univ/Johns Hopkins Univ jointly developed 4D XCAT phantoms for Monte Carlo simulation. Does NCAT phantom have to do with them?</div><div><br></div><div>I would greatly appreciate it if you can help with these questions or point me to anybody who can help. </div><div><br></div><div>Best regards,</div><div><br></div><div>Howard</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, Feb 6, 2020 at 12:30 AM 강한규 <<a href="mailto:lovehangulp@naver.com">lovehangulp@naver.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div><div style="font-size:10pt;font-family:Gulim,sans-serif"><p>Dear Howard,</p><p> </p><p><span style="font-size:10pt">Attached is the manual of <b>GATEv6.2 X-ray CT simulation</b> with a non-voxelized phantom.</span> </p><p>I'm sorry that the manual is written in Korean. </p><p>If you need an English version, please let me know.</p><p> </p><p>You can also perform X-ray CT simulation with a <b>voxelized phantom</b> as below.</p><p>The GATE output (projection data) was reconstructed with OSCaR software.</p><p>In my opinion, the NCAT phantom could also be implemented easily by modifying the GATE macro files.(Please refer the my previous mail about NCAT phantom)</p><p> </p><p> </p><p><img src="cid:1701af164fd7cccbb161"> </p><p> </p><p>Hopefully, my answers would be helpful for your X-ray CT simulation with NCAT voxelized phantom.</p><p> </p><p>If you have any question, please let me know.</p><p> </p><p>Best regards,</p><p> </p><p>Han Gyu Kang, Ph.D.</p><p> </p><p>Imaging Physics Group, NIRS-QST, Japan.</p><p> </p><p style="font-size:10pt;font-family:sans-serif;padding:0px 0px 0px 10pt"><span>-----Original Message-----</span><br><b>From:</b> "Howard"<<a href="mailto:lomahu@gmail.com" target="_blank">lomahu@gmail.com</a>> <br><b>To:</b> "강한규"<<a href="mailto:lovehangulp@naver.com" target="_blank">lovehangulp@naver.com</a>>; <br><b>Cc:</b> <<a href="mailto:gate-users@lists.opengatecollaboration.org" target="_blank">gate-users@lists.opengatecollaboration.org</a>>; <br><b>Sent:</b> 2020-02-06 (목) 12:02:28 (GMT+09:00)<br><b>Subject:</b> Re: [Gate-users] How to import NCAT phantom to Gate (NCAT phantom with ECAT PET)<br> </p><div dir="ltr"><div dir="ltr"><div>Hi Dr. Kang,</div><div> </div><div>I am trying to simulate respiratory motion with X-ray CT.
