Application of xeroradiography for pneumencephalography.

The feasibility of xerotomography with pneumencephalography is demonstrated. One of the advantages of a xerotomogram is that it reduces the lack of sharpness caused by tomography. The wide recording latitude of a xerotomogram makes a more detailed evaluation of the bone structure and the outlines of the soft tissue possible when these are contrasted be means of air. The characteristic edge effect of a xerogram also facilitates better detection of the small structures which are less well discerible on a film tomogram.
