How should a patient be placed within a cephalostat for a lateral cephalometric skull radiograph?

For obtaining a lateral cephalometric skull radiograph, positioning the patient correctly within the cephalostat is crucial for accurate imaging. The correct method of positioning involves aligning the patient so that the x-ray beam is perpendicular to both the midline sagittal plane of the skull and the image receptor. This alignment ensures that the structures of the skull are properly captured without distortion and that the resulting radiograph provides an accurate representation of the craniofacial anatomy.

Correct axial alignment minimizes errors in the measurement and analysis of skeletal relationships, which are essential in orthodontics and other dental disciplines. This precise alignment is vital for evaluating growth patterns, diagnosing orthodontic issues, and planning treatment. Other positioning methods may lead to inaccuracies, which could compromise the analysis and treatment planning processes.
