<div dir="ltr">Hello,<div><br></div><div>I am new to RTK. Thanks to the creators for building such a great toolset. </div><div><br></div><div>I found information about RTK because I was trying to perform a CBCT recon based on a short scan obtained from Varian OBI.</div>
<div><br></div><div>In my specific case, I have 372 projection images (both in the original Varian .hnd format, and raw projection format converted with plastimatch) scanned over 220 degrees of the phantom. </div><div><br>
</div><div>I have followed the instructions on the wiki page and successfully installed RTK. However I could not find much documentation regarding the parker short scan weighting tool. I did find some prompts after typing into command line:</div>
<div><br></div><div><div>user@Cluster:~/RTK/RTK-bin/bin$ ./rtkparkershortscanweighting</div><div>./rtkparkershortscanweighting: '--geometry' ('-g') option required</div><div>./rtkparkershortscanweighting: '--path' ('-p') option required</div>
<div>./rtkparkershortscanweighting: '--regexp' ('-r') option required</div><div>./rtkparkershortscanweighting: '--output' ('-o') option required</div></div><div><br></div><div>Judging from the name, I suppose this rtkparkershortscanweighting tool is to preprocess the projection data, but I am not sure. I am also puzzled at what I should specify for each of the options, especially the geometry option (how should I generate the geometry file, etc). I googled but to no avail. </div>
<div><br></div><div><br></div><div>Could somebody direct me to a tutorial, or shed some light on the usage of the command line tool?</div><div><br></div><div>Thanks very much!</div><div><br></div><div>Best Regards,</div><div>
