Abstract:
A hyper-transparency compensating device for a gantry mounting radiography apparatus, the apparatus having a first and second opposite arms rotatable around a rotation axis, the first arm supporting an X-ray source and the second arm supporting an X-ray tube amplifier that is in registry with the X-ray source, the apparatus being used for radiographing an organ having a median plane in which the rotation axis is substantially lying, the device comprising:at least one compensating filter defining a filter plane, the compensating filter having a longitudinal rotation axis;a supporting assembly to pivotally support the compensating filter and allow a rotation thereof around the longitudinal rotation axis, the supporting assembly being connectable to the first arm of the gantry mounting apparatus, in front of the X-ray source and in registry with the X-ray source and the hyper transparency area while keeping the filter plane parallel to the reference plane during rotation of the arms around the axis.
