Dodger filters represent a very great improvement in the usual technique of modulation of X-Ray beams, The mobility of the filters permits one to use them efficaciously in numerous situations encountered in common radiodiagnosis. Original optical methods ensure perfect adaptability of the filters to morphology and density of the structures examined. The shape and structure of the filters prevent formation of artefacts ducts mains interference on the X-Rays. To an improvement in the quality of the films, may be adder reduction in exposure of the examined subjects. This apparatus, easy to bring into operation, may thus be used more widely in numerous branches of radiodiagnosis, in particular, in cerebral and visceral angiography.
