Xeroradiography and Its Clinical Application to Oto-Laryngology

Abstract

Xeroradiography, a kind of electrostatic and dry photographic method for radiography, has the advantages of higher definition and wider latitude than ordinary roentgenography. The authors have developed the xeroradiographic technique for clinical use and explored the diagnostic application of this technique to problems in the field of oto-laryngology.

The limitations imposed by the delayed recovery of the selenium plate during repeated uses were almost eliminated by using a special recovery promoting instrument. Various regions of interest to the oto-laryngologist, such as the temporal bone, the paranasal sinuses and the larynx were studied.
