<div dir="ltr">Hello,<div><br></div><div>I am attempting to bin the ASCII output of an ECAT system simulation to sinogram space. I am having some trouble with this as I cannot find anything in the user guide which specifically lists how crystals in a module are indexed. Could someone please clarify this for me. </div><div><br></div><div>For example, if I have--in the same module with an 8x8 crystal array--coincidence events in crystals 1 and 2, would these crystals both belong to the same crystal ring, or adjacent crystal rings? Alternatively, in an 8x8 array, are crystals 1-8 in the same ring, with another ring formed by crystals 9-16?</div><div><br></div><div>Thank you for your assistance.</div><div><div><br></div>-- <br><div class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr">Karl Spuhler<div><br></div><div>SUNY Stony Brook</div><div>PhD Student</div><div>(845)249-6836</div><div><h1 style="font-weight:normal;color:rgb(51,51,51);margin:0px 0px 0.4em;line-height:1;font-family:arial,sans-serif,helvetica"><br></h1></div></div></div>
