<br>
My name is Anaïs, I’m a student in computer sciences, and I'm currently doing my internship, which consists partly to do a tomographic reconstruction.<br>
<br>
I use rtk to reconstruct my model, but I have problems when I use rtkforwardprojections and rtkfdk with –like or –dimension.<br>
Indeed, if I use them with the default parameters, it works correctly, but when I specify –like or certain values of –dimension the reconstruction isn’t correct.<br>
For instance if I use the example file muCT.mha as my model, it works perfectly with the default parameters, but if I choose –like=muCT.mha, in my reconstruction file there are mostly black voxels.<br>
I also saw that the example in the scripts for forward projections (<a href="http://wiki.openrtk.org/index.php/RTK/Scripts/ForwardProjection" rel="noreferrer" target="_blank">http://wiki.openrtk.org/<wbr>index.php/RTK/Scripts/<wbr>ForwardProjection</a>) works when the spacing, the origin, and the dimension specified to rtkfdk are the same than the model.<br>
<br>
I wanted to know why it doesn’t works when I use –like.<br>
Is there a relation between the geometry and dimensions and that’s why I have problems (for instance due to the source being too close to the object)?<br>
<br>
<br>
Thank you very much.<br>
<br>
Anaïs<br>
