Coordinate System

We use the following standard orientation to display data:

  • +x points in right direction (sometimes a bubble or some other artefact may indicate left and right)
  • +y points in anterior direction
  • +z points in superior direction
  • -x points in left direction (sometimes a bubble or some other artefact may indicate left and right)
  • -y points in posterior direction
  • -z points in inferior direction

As the explanation is a bit tricky, here another try: If you look from the front (anterior) your position is at +y and you look into -y direction.
