Operating system:Win10  
Slicer version:4.10.2  
Expected behavior: Normal View  
Actual behavior: Coronal View is distorted

Hello,  
I am new to evaluation of CT-Scans. When i import my tiff-files from a CT-scan to Slicer, the coronal view is distorted as shown in the picture

 ![twisted](https://us1.discourse-cdn.com/flex002/uploads/slicer/original/3X/0/f/0fd0b074baff2ae6ba1be3946e54142da322e827.png)

I am not sure how to avoid this behavior.

Thank you in advance!

That appears to be a set of projection images, not a volume. You need reconstruct, either with the scanner itself or with another program.
