I double I made some mistakes since the scatter fraction seems not reasonable compared to published papers. Could anyone send me a macro file for scatter fraction with a patient bed? Any commercial (human) systems are fine.<br><br>Thank you very much.<br><br>One suggestion for GATE group: could you provide a set of macro files (examples) for NEMA testing? I think it is very helpful for new GATE users (like me).<br><br><div> </div>Hongwei<div><br></div></div><br> </body></html>
