Hello,
It seems that there are a lot of coordinate systems involved in Slicer.
I was trying to find a tutorial explaining the different coordinate systems and transformations among each other, however, failed to find a good one.
Specifically,
-
How many Coordinate Systems (CSs) are involved Slicer? (e.g., IJK, XYZ, SliceNode? VolumeNode? RAS? LAS, LPI, RPI…)
-
How are those CSs employed in Slicer? (e.g., what exactly is a coordinate of Slice? and what does the matrix of SliceToRAS do?)
-
Any resource or tutorial that explains how the principles of different transformation matrixes mathematically?
Thank you very much!
