A reliable positioning device for dorsoventral cephalometric radiography of the rat

Lab Animal volume 37, pages 127–131 (2008)Cite this article

Abstract

In dental research, dorsoventral cephalometric radiography is often used to assess skull growth and dental movement in rat models. To ensure that images can be reproduced, radiographers must use a cephalostat to maintain the rat's head in a consistent position across imaging sessions. The authors describe a positioning device they designed that connects easily to a standard dental X-ray machine. The device enabled researchers to position rats repeatedly for radiographic imaging with very little variation.
