Radiol. 428 (heading) New method of differentiation in roentgenography (planigraphy). 1938Radiology XXX. 655/1 The authors discuss the various methods of planigraphy and the problem of radioscopy of a plane. 1942Amer.

XLVII. 83 (heading) The value of body section roentgenography (planigraphy) for the demonstration of tumors, non-neoplastic disease and foreign bodies in the neck and chest. 1967Investigative Radiol. II. 259/1 Although conventional linear planigraphy does not approach the precision attained with the more elaborate movements afforded by the ‘Polytome’, ‘Mimer’ and others, its efficiency can be improved. 1986B. Keane in T. F. McAinsh Physics in Med. & Biol. Encycl. II. 671/1 Where it is particularly desired to obtain a three-dimensional dissection of some feature, the method of body-section radiography is used.
