<div dir="ltr">Dear S, Megha Singh<div><br></div><div>If you have the information about the shape of the bow-tie filter (i.e. the height h=h(x) of the filter in the fan plane, or its angle dependence), you can use the wedge geometrical shape, which is available in GATE, to construct the whole filter as a sum of many wedge bodies with tiny x-dimensions to approximate the real shape of your filter.<br></div><div><br></div><div>Best regards,</div><div>Alejandro Coloma</div></div><div class="gmail_extra"><br><div class="gmail_quote">2014-10-29 5:01 GMT-05:00 <span dir="ltr"><<a href="mailto:meghatuyan@yahoo.co.in" target="_blank">meghatuyan@yahoo.co.in</a>></span>:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div style="color:#000;background-color:#fff;font-family:HelveticaNeue,Helvetica Neue,Helvetica,Arial,Lucida Grande,Sans-Serif;font-size:14px"><div><span>Dear experienced gate users,</span></div><div style="color:rgb(0,0,0);font-size:14px;font-family:HelveticaNeue,'Helvetica Neue',Helvetica,Arial,'Lucida Grande',sans-serif;font-style:normal;background-color:transparent"><span><br></span></div><div style="color:rgb(0,0,0);font-size:14px;font-family:HelveticaNeue,'Helvetica Neue',Helvetica,Arial,'Lucida Grande',sans-serif;font-style:normal;background-color:transparent"><span>I am having hard time to model the bow-tie filter geometry (fixed or dynamic) for fan-beam CT using GATE?
