15.5.2 Forward head posture vs Normal posture: X-ray path
When the patient is in a normal posture, the "distance of the cervical region through
which the X-ray passes" is short (orange arrow), so attenuation is small, but when the
patient is in the Forward head posture, the "distance of the cervical region through
which the X-ray passes" is relatively long Because of this (red arrow), the attenuation
is large. Therefore, it may occur as artifacts in the image depending on the degree of
attenuation.
