ABSTRACT
Positioning for lateral supine skull (anterior aspect) projection. https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781315382210/8ca82e7c-bd07-4171-b4f5-ebaded57b5b3/content/fig2_77a.jpg" xmlns:xlink="https://www.w3.org/1999/xlink"/>
The patient lies supine with the head raised and immobilised on a non-opaque skull pad. This will ensure that the occipital region is included on the image.
The head is adjusted such that the median sagittal plane is perpendicular to the table/trolley and the inter-pupillary line is perpendicular to the image receptor.
The image receptor is supported vertically against the lateral aspect of the head (region of interest) parallel to the median sagittal plane, with its edge 5 cm above the vertex of the skull.
