摘要: The invention discloses a mammary gland X ray system and collimator thereof. comprises filter disc switching mechanism shooting field adjusting mechanism, wherein the are oppositely arranged in vertical direction; supporting plate with through hole, rotating which is rotationally on corresponds to lens at least two discs, discs spaced mode, located surface, facing of plate; window multiple plates surrounding side window; hole communicated from passage for penetration rays, rotates rotation. By adoption within different filtering ranges, energy spectrums rays irradiating breasts patient achieve imaging effects; irradiation range can be limited, other portions prevented being irradiated.
