Penumbra


Definition:

  • (n.) An incomplete or partial shadow.
  • (n.) The shadow cast, in an eclipse, where the light is partly, but not wholly, cut off by the intervening body; the space of partial illumination between the umbra, or perfect shadow, on all sides, and the full light.
  • (n.) The part of a picture where the shade imperceptibly blends with the light.

Example Sentences:

  • (2) Analysis of the penumbra width of cross dose distributions, as a function of field sizes, allowed us to postulate that the dmax shift could be due to the phantom scattered photons, which in turn were generated by the collimator scattered photons.
