Hi everyone.
I have a very simple question that maybe @zivy can answer (based on previous related topics).
I want to generate a rotational MIP around a specified axis with an image that has not an unit direction cosine matrix.
Following other topics on the forum (rotational around specified axis, Rotational MIP) I successfully do the rotational MIP around specified axis but the MIP is not on the proper axis of the image (meaning that the image stack is inclined).
How can I get image in the image coordinate using direction cosine matrix + origin? (easiest way. So I can get an image with unit direction cosine matrix and do all my transformation in this space).
Or
how I can used maximum intensity projection along a specified axis? (and Keep the physical coordinates system for the MIP).
Not clear what is the desired output vs. what you obtain. Possibly provide some drawings/images to clarify?
If the goal is to easily generate rotational DRRs, possibly look to plastimatch, specifically its DRR command line tool, or to RTK which I think has similar functionality (not sure about this one).
yes my explanation is unclear but I finally solve my problem.
So the idea was to get a rotating MIP on an inclined image stack. Do the rotation around the image axis (using direction cosine matrix). The problem I was facing is that for the resampler, I used as OutputDIrection an unit direction cosine matrix, instead of the image direction. But with the image direction cosine, it is working.
