Photofluorographyphotofluorography[¦fōd·ō·flu̇′räg·rə·fē]Photofluorographya radiographic technique in which an X-ray image of an object is photographed from a fluorescent screen. The fundamental principles of photofluorography were developed by the Italian scientists A. Battelli and A. Carbasso and the American scientist J. M. Bleyer immediately after the discovery of X rays. In photofluorography, the image of the object is reduced in size. A distinction is made between small picture frame (24 × 24 or 35 × 35 mm) and large picture frame (70 × 70 or 100 × 100 mm) photofluorography. The diagnostic capabilities of large picture frame photofluorography approach those of roentgenography. Photofluorography is used primarily to examine the organs of the chest, the breasts, and bones. The main advantage of photofluorography in comparison with other roentgen diagnostic techniques is the possibility of mass examinations to disclose diseases in their latent period. Photofluorography is performed in doctors’ offices and clinics as well as in mobile units, such as vans and railroad cars. REFERENCESSee references under ROENTGEN DIAGNOSIS.E. A.
