I think I have actually solved my problem thanks to the reply to this post.

> Hi Csaba Thank you for the response. I did actually also try the nightly build and the behavior was the same. I was using the sample “MR US prostate” data and that data was indeed rotated in the axial view. However after rotating it as you suggest, I cannot contour it. the moment I right-click or type “a” the contour disappears. Is that behavior expected? Kind regards, Bo PS. I would not have bothered you had I only had problem with the ultrasound data.The stripey phenomenon was also a probl…

Now I first create a ROI, rotate my volume but not the ROI and then crop so the new cropped volume is aligned to the slicer axis and the segmentation tools work fine.

Sorry for my first post, that was really easy in the end.
