Default center of rotation

Support

Hello,

I am rotating an image in the Transforms module. I am wondering what the default center of rotation point is, and if I can extract that point in world coordinates? Or is this simply the image origin?

Thank you.

Hi, Janneke. The default center of rotation is the origin of the physical coordinates, where (R, A, S) = (0, 0, 0) mm. This is typically not the voxel with index (0, 0, 0) of the image, which is where the image origin is.

Hi Fernando,

Thank you for your quick response.
That makes sense and solves my problems, thank you.
