Study of the Central X-ray Incidence Angle of Anteroposterior Projection in Radiography of the Cervical Spine

Abstract

We examined the central X-ray incidence angle of anteroposterior projection in radiography of the cervical spine.Measurements of incidence angle determined index on surface as connect line with externalaudiotory meatus and acromial angle of scapula when we take a lateral cervical spine radiography, slope of it connect line decided incidence angle of anteroposterior projection.This study included 300 clinical patients(141 female and 159 male).For reads right of this index , we measured cervical lordosis wrote Borden's and angle of intervertebral discs from the radiography which was obtained, and analyzed combines sexuality and age.Cervical spine configurations could be grouped into 7 types and further divided into 14 sub-types based on lateral cervical spine radiography. Relationship of incidence angle and angle of intervertebral discs, in other words, reliability of the incidence angle read coefficient of correlation coefficient 0.75-0.94 values price into the all classification.The level of statistical significance wasset at 1%.This method is based on the curvature and inclination of the cervical spine of each patient, and then it's measurement way for radiography technique in clinical.
