2. The X-ray field must extend beyond all edges of the active image receptor. The X-ray field must not
extend beyond any edge of the image receptor by more than that quoted in
For each of the exposure configurations below, enter the determined deviations between the edge of
the X-ray field and the edge of the image receptor in the plane of the image receptor for each of the
four XR-M film strips. That is, the value Z
2-2.
For each of the exposure configurations below, determine whether the action limit for each edge has
passed or failed according to the table below (see illustration 1 on
