I have a problem like this. Many different dicoms are loaded in my project. In the loaded analysis, each of my 3D images comes at a different angle. I’m not sure why they all come at different angles.

But my main problem is that since they all come from different angles, my green, red, blue planes, that is, those lines that show the sections of the 3D image, in short, the axial sagittal coronal lines, can be wrong.

If there is a different orientation of dicom data, you’d have to set camera position and focal point so that the direction of projection is perpendicular to the slice plane. [VolView](https://volview.kitware.com) does this.

Thank you very much, I fixed it.
