Question: 1 / 400
The true lateral position of the skull requires which of the following alignment principles?
MSP perpendicular to the IR
Interpupillary line perpendicular to the IR
IOML parallel to the IR
Both B and C
In achieving a true lateral position of the skull for radiographic purposes, the alignment principles are crucial to ensure accurate representation and minimize distortion in the images. When the interpupillary line is positioned perpendicular to the image receptor (IR), it ensures that the patient's head is rotated properly and that the orbits are not overly foreshortened or elongated in the final image. This orientation is essential for maintaining the anatomical fidelity of the lateral view of the skull.
Additionally, having the infraorbital meatal line (IOML) parallel to the IR supports appropriate positioning of the skull in relation to the imaging plate. This alignment helps in visualizing the anatomical structures accurately and achieving a true lateral projection, which is vital for diagnosing various conditions related to the skull.
Therefore, both the correct alignment of the interpupillary line and the IOML are necessary for a true lateral position, making the combination the most accurate approach for positioning the skull in lateral radiography.
