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.
多吉尔滤光片在X射线束调制的常规技术方面有了很大改进。滤光片的可移动性使其能够在普通放射诊断中遇到的多种情况下有效使用。原始光学方法确保滤光片能完美适应所检查结构的形态和密度。滤光片的形状和结构可防止在X射线上形成伪影、管道主干扰。除了提高胶片质量外，还可减少被检查者的辐射暴露。这种易于操作的设备因此可在放射诊断的众多分支中更广泛地使用，特别是在脑血管造影和内脏血管造影中。
