Operating system: Windows  
Slicer version: 2.0  
Expected behavior:  
Actual behavior:  
I was trying to load some US patient data into the slicer. When I load the data, all slices are interpreted as axial, even though there are sagittal slices. Is there a way to fix this?

You can orient the volume by using Transforms module: create a new linear transform, apply it to the volume, and adjust rotation sliders.

What if I have one 2-D cross section each along x-z and y-z planes:

Is there some way to approximate a volume for this?

If you know the position of each slice then create a sequence file and load that using sequences extension (see details [here](https://discourse.slicer.org/t/importing-of-position-tracked-ultrasound-sequence/4094/9)).

Once you have the slices in their correct position, you can reconstruct a shape from two slices using “Surface cut” effect in Segment Editor module (install SegmentEditorExtraEffects extension to get this effect).

This works amazingly well for generation of breast tumor 3D model from a few position-tracked 2D ultrasound images - see more information [here](http://www.slicerigt.org/wp/breast-cancer-surgery/).
