X-ray protection device
A shielding arrangement for an x-ray apparatus, preferably for mammography examination is disclosed, and comprises at least an x-ray source, a collimator arrangement and a detector assembly, whereby the collimator is arranged between the x-ray source and the detector assembly and through which x-rays pass. The shielding arrangement, at least partly made of x-ray blocking material and provided for blocking, scattering and/or reflecting x-rays is arranged, at least partly, in a space between the x-ray source and collimator.
1. An x-ray apparatus, comprising:
a vertically oriented support member;
a collimator and a detector assembly supported by and extending laterally relative to said vertically oriented support member with said collimator disposed above and vertically displaceable relative to said detector assembly;
an x-ray source disposed above said collimator and said detector assembly with said collimator being arranged between said x-ray source and said detector assembly in such a way that x-rays pass through said collimator; and
a shielding assembly arranged between said x-ray source and said collimator, wherein said shielding assembly and said x-ray source are displaceable relative to each other.
2. The x-ray apparatus according to claim 1 , wherein said shielding assembly is a box-shaped structure provided on a housing for said collimator.
3. The x-ray apparatus according to claim 1 , wherein said shielding assembly is a telescopic structure between said x-ray source and said collimator.
4. The x-ray apparatus according to claim 1 , wherein said shielding assembly is an accordion shaped folding structure between said x-ray source and collimator.
5. The x-ray apparatus according to claim 1 , wherein said shielding assembly is at least partly made of an x-ray blocking material.
6. The x-ray apparatus according to claim 1 , wherein said collimator provided with said shielding assembly and said detector arrangement are displaceable relative to each other.
7. The x-ray apparatus according to claim 1 , wherein said shielding assembly is displaceable substantially vertically.
8. An x-ray apparatus, comprising:
a vertically oriented support member;
a collimator and a detector assembly supported by and extending laterally relative to said vertically oriented support member with said collimator disposed above said detector assembly;
an x-ray source disposed above said collimator and said detector assembly with said collimator being arranged between said x-ray source and said detector assembly in such a way that x-rays pass through said collimator; and
a shielding assembly arranged between said x-ray source and said collimator, wherein said shielding assembly and said x-ray source are displaceable relative to each other;
wherein said shielding assembly comprises a number of boxes insertable into each other, with varying sizes, the largest box being closest to the collimator.
9. The x-ray apparatus according to claim 8 , wherein at least one wall of each box is inclined.
