The NUCCA doctor takes three very precise cervical x-rays (lateral, nasium, and vertex views).
The x-ray equipment is aligned to reduce radiation and unequal magnification to the greatest extent possible.
All three views are carefully measured and analyzed and a proper force vector for the atlas correction is determined.
