density

Pronunciation: den'si-te

Definition:

  1. The compactness of a substance; the ratio of mass to unit volume, usually expressed as g/cm3 (kg/m3 in the SI).
  2. The quantity of electricity on a given surface or in a given time per unit of volume.
  3. radiologic physics the opacity to light of an exposed radiographic or photographic film; the darker the film, the greater will be the measured density.
  4. clinical radiology a less exposed area on a film, corresponding to a region of greater x-ray attenuation (radiopacity) in the subject; the more light transmitted by the film, the greater the density of the subject will be; this is not actually the opposite of sense 3, because one concerns film density and the other subject density.

[L. densitas, fr. densus, thick]
