<div dir="ltr"><div><div>Hi,<br></div>The typical solution (e.g., in clincial scanners) is to reconstruct the field-of-view of the scanner (every point in space that is seen by all source positions) because you know this is the only area of space where your reconstruction is going to be accurate. rtkfieldofview generates this FOV.<br></div>Simon<br></div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, May 12, 2016 at 6:12 AM, AMJAD N <span dir="ltr"><<a href="mailto:amjad.n.cet@gmail.com" target="_blank">amjad.n.cet@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Hello users,<div><br></div><div>I have successfully implemented CBCT reconstruction using both CUDA and CPU method.
