The real rotating centre is in the middle of the line between points a and b. This new crossing
point must be inside the ±1mm limits from the ball phantom x-line and y-line crossing point. If
it is, adjust the lights to cross in this point.

In case the new crossing point is not inside the ±1mm limits from the ball phantom x-line and
y-line crossing point, you must readjust the patient positioning mechanism, see section 2.6
