laminagraph Radiology.|ˈlæmɪnəgrɑːf, -æ-|
Also lamino-.
[f. lamina + -graph.]
= tomograph. (Originally a particular design of tomograph.)
1938J. Kieffer in Amer. Jrnl. Roentgenol. XXXIX. 497/1 The laminagraph is a device embodying the principle of roentgenographic body sectioning, or planigraphy... It was built at the instigation of, and in co⁓operation with, the director, Dr. Sherwood Moore, who named it (lamina: a thin layer). 1942Surg., Gynecol. & Obstetr. LXXV. 508/2 The last case..demonstrates the increase of bone detail by laminagraph as compared to the usual x-ray examination. 1960Jrnl. Speech & Hearing Disorders XXV. 137/2 With a multilayer laminagraph cassette or film-holder, it is possible to record simultaneously a number of adjacent planes or body sections with a single exposure.
Hence ˌlaminaˈgraphic a., of or pertaining to laminagraphy; ˈlaminagram, a radiograph taken using a laminagraph; lamiˈnagraphy = tomography.
1938Amer. Jrnl. Roentgenol. XXXIX. 507/2 The extent of the layer sharply rendered during laminagraphic motion is limited only by the size of the object roentgenographed and by the size of the film used. Ibid. 503/2 Satisfactory chest laminagrams can be made in one second. 1939Radiology XXXIII. 560/1 The last method has also been spelled ‘laminography’ by various authors. Ibid. 560/2 Laminagraphy—a method whereby body-section roentgenography is accomplished by motion of the tube and film in planes parallel to one another and at any angle to the film surface. 1942Urologic & Cutaneous Rev. XLVI. 706/1 Laminography permits the roentgenographic delineation of structures at different levels... Laminograms are made by synchronously moving the X-ray film and the tube carrier in opposite directions. 1960Jrnl. Speech & Hearing Disorders XXV. 137/2 Laminagraphy is used most advantageously when skeletal structures are not clearly visualized with standard techniques. 1966Amer. Speech XLI. 229 Clear images of vocal fold cross-sections during actual phonation by laminagraphic X-ray photographs. 1968H. O. Anger in Gottschalk & Beck Fund. Probl. in Scanning xiv. 195 A tomographic or laminographic series will be obtained from a single rectilinear scan. 1969R. & E. Brecher Rays xix. 258 The modern technique, known generally as body-section radiography but also as laminography, stratigraphy, tomography, and planigraphy, depends upon imparting a reciprocal motion to the X-ray tube and film. 1971Jrnl. Amer. Med. Assoc. 16 Aug. 927/2 The ability to record both dynamic studies and ‘thick’ laminagrams..reduces the time necessary for the physician to view the films. 1971Radiology CI. 617/1 A rounded soft-tissue mass was seen near the canal of the infraorbital nerve at laminagraphy. |
