title: [A new rare earth intensifying screen: lanthanum oxybromide (Quanta III - Dupont): relative speed, resolution and image quality (author's transl)].
abstract: Some physical and diagnostic characteristics of a new rare earth screen (lanthanum oxybromide: Quanta III) were evaluated and compared to those of conventional calcium tungstate (Hi-Plus-Dupont). The speed, resolution and clinical acceptance were analyzed using the same film (Cronex 4 - Dupont). This new system allows a significant X-ray exposure reduction with little or no loss of overall diagnostic performance.
