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.
气脑造影体层摄影的可行性已得到证实。干板体层摄影的优点之一是它减少了体层摄影造成的清晰度不足。当通过空气对比时，干板体层摄影的宽记录宽容度使对骨结构和软组织轮廓进行更详细的评估成为可能。干板X线照片的特征性边缘效应也有助于更好地检测在胶片体层照片上较难分辨的小结构。
