<div dir="ltr">Helllo Robert,<br>In RTK, the rotation axis is by default y so slice thickness would be y resolution. I would indeed chose the v pixel spacing at the center of rotation for the y direction spacing. For x and z (axial slice) pixel spacing, it depends on both the detector pixel spacing in the u pixel spacing and the number of projections around the object. I recommend reading section 8d of <a href="http://theses.insa-lyon.fr/publication/2016LYSEI085/these.pdf">http://theses.insa-lyon.fr/publication/2016LYSEI085/these.pdf</a> for a few words on that.<br>Simon<br></div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Mar 15, 2018 at 8:53 AM, "Robert Calließ" <span dir="ltr"><<a href="mailto:Robert.Calliess@gmx.de" target="_blank">Robert.Calliess@gmx.de</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div style="font-family:Verdana;font-size:12.0px"><div>Hello,</div>
<div>I have a question according to the z resolution of reconstructed volumes.</div>
<div>As far as I know, we do determine the xy resoltuion by dividing the </div>

<div>What about the z resolution ? Do we assume that it is like the resolution in</div>
<div>x or y ? How to determine the maximum z slices.</div>
<div> </div>
<div>Then, is the z resolution the thickness of a slice or the distance between two</div>
<div>adjacent slices ?</div>
