Recent government legislation in many countries around the world calls for specific alignment accuracy between x‐ray and light beams for diagnostic x‐ray machines. This technical report describes an alignment model that can be used to check the coincidence of both the x‐ray field and its central ray with the light field and its cross hairs.
