I recently started using Slicer 4.13-2021-10-10 and noticed that some images are loading in a near ac-pc alignment even though they were not acquired in that way, and no ac-pc transformation has been applied. I’ve used earlier versions of Slicer, e.g., Slicer 4.11-20200930 with no issue on image orientation.
Here is an example:
Screenshot is from Slicer 4.11-20200930 that displays the original orientation:
Screenshot from Slicer 4.11-20200930 after ac-pc transformation that displays correct orientation:
Screenshot from Slicer 4.13-2021-10-10 (with no ac-pc transformation applied; only original image loaded):
The ac-pc fiducials do not line up for the last scan, which makes sense since no ac-pc transformation has been applied. When I apply the ac-pc transformation, the ac-pc fiducials do align but the image display is oriented obliquely since all three dimensions are moving in the Data Probe window when moving the cursor:
Any idea on how to get the image to correctly along the ac-pc axis after transformation like the earlier Slicer version?
Thanks for your help,
