A wheelchair can also be • used in performing this incidence. This offers back support and provides greater • stability in maintaining position. • ► Position of the Party: • • Raise the patient's chin and hyperextend the neck, if possible, until the LIOM is parallel to the RI • (see Remarks). • • Support the patient's head at the apex. • • Align the PSM perpendicular to the midline of the grid device surface or • table/image device, avoiding tilting or rotation. • bench press • With the patient in the supine position, extend the patient's head over the edge of the table and • sustain the K7 grid and the head as shown, keeping the LIOM parallel to the RI and perpendicular • to the CR. If the table does not tilt or is too small to hold the RI (Fig. 11-116), use a • pillow under the patient's back to allow sufficient neck extension. • upright • If the patient is unable to extend the neck sufficiently, compensate by angling the central radius • to remain perpendicular to the LIOM. Depending on the material used, RI can also be • angled to maintain perpendicular relationship with the RC (eg with an imaging device • adjustable vertical). • This position is very uncomfortable for patients in the standing or supine position; perform it so • quickly as possible. • ► RC: • • CR is perpendicular to the infraorbitomeatal line. • • Center about 4 cm inferiorly to the mandibular symphysis or midway between the gonians. • • Centralize the RI to the RC. • ►RI: 18x24 (Longitudinal) • ►DFOFI: 1m • ------------------------------------------------- ---------------------------------- • *Source: Kenneth L.
