I can only think of three: the central ray, the body part and the image receptor. What am I missing? |

I think in that context, the x-ray tube and the central ray should be the same. You have to have the tube lined up so that the central ray is perpendicular. |

The central ray refers to the entry and exit point of the CR and the tube should be perpendicular to the IR. Kind of the same, but refering to different parts  |
