Hi Guillaume,<br>
I think this issue has been fixed with this commit:<br>
<a moz-do-not-send="true" class="moz-txt-link-freetext"
href="https://github.com/SimonRit/RTK/commit/c20b469cb0ccca0a93a16835aba38f9dae64ff0b">https://github.com/SimonRit/RTK/commit/c20b469cb0ccca0a93a16835aba38f9dae64ff0b</a><br>
Are you using a version that is older? If yes, maybe try to update
RTK.<br>
Thanks for the report,<br>
Simon<br>

Good morning Simon,<br>
<br>
I sent this mail to the rtk list but its currently held due to
the size of the screenshots. Anyway I was wondering what you
thought was the issue. If you prefer to wait for the mailing
list no worries.<br>
<br>
Thanks<br>
Guillaume<br>

<pre>Dear users, developers,
I am exploring the 4D functionality of rtk and was experimenting with
rtkfourdfdk as starting point, using a 1 minute scan of the CIRS moving
phantom. I used the attached phase signal along with the settings I
normally use with rtkfdk (so far those worked fine in 3D, see below for
the command used).
I tried the default 10 phase bin reconstruction and I obtain a
corresponding image. The issue I observe is that when I open the data in
my viewer (vv in this case) for each phase bin the reconstructed images
have difference "initial angle", in other words rotated with respect to
each other (see snapshots). The rotation increases with bin# up to the
8th bin (numbered 7 in snapshots), for the 9th bin the angle "resets" to
a lower value and the trend continues for the few remaining bins. This
seems somewhat related to the phase per projection (the phase wraps
after the 7th projection).
rtkfourdfdk --geometry geometry.xml --path path --regexp
''projections.mha'' --output CBCT_4D.mha --verbose --spacing 1,1,1
--hann 5.0 --hannY 5.0 --pad 0.2 --hardware cuda --dimension 410,264,410
--origin -205,-131,-205 --signal phase.txt
Any guidance on this topic would be appreciated.
Regards
Guillaume
