ABSTRACT
Positioning for a reverse Towne’s 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_73a.jpg" xmlns:xlink="https://www.w3.org/1999/xlink"/>
This projection is usually undertaken with the patient in the erect position facing the erect Bucky/image receptor, although it may be performed with the patient prone on the X-ray table.
Initially, the patient is asked to place their nose and forehead against the image receptor. The head is adjusted to position the median sagittal plane at right angles to the image receptor so it is coincident with its midline.
The orbito-meatal baseline should be perpendicular to the image receptor.
The patient may place their hands on the Bucky/receptor for stability.
