latitude

 [lat´ĭ-tood]
the recording capability of x-ray film.
contrast latitude the ability of a film to record differences in density.
film latitude the ability of an emulsion to record a wide range of densities.

lat·i·tude

(la'ti-tūd),
The range of light or x-ray exposure acceptable with a given photographic emulsion. See: latitude film.
[L. latitudo, width, fr. latus, wide]

latitude

Etymology: L, latitudio, breadth
the ability of an x-ray imaging system to produce acceptable images over a range of exposures. If a system has wide latitude, it is possible to image parts of the body that vary in thickness or density with only one exposure. A system of lesser latitude would require a lower exposure over the thin section and a greater exposure where the absorption was greater.

The range of light or x-ray exposure acceptable with a given photographic emulsion.

latitude (lat´itood),

n the range between the minimum and maximum film exposures to radiation that yields images of structures of which photographic density differences are discernible under normal viewing conditions. Latitude mainly varies directly with kilovoltage and inversely with contrast. See also contrast.
