| 摘要 |
The invention relates to a diaphragm (3) for X-ray diagnosis equipment, having a pair of parallel diaphragm plates (5, 6) made from radiation-absorbing material, which can be adjusted in opposite directions towards and away from one another. One lamella (21, 22) each, made from radiation-absorbing material, is pivotably mounted after each diaphragm plate (5, 6) seen in the direction of radiation and is guided by guiding means (16, 17) in such a way that it moves with the end of the associated diaphragm plate (5, 6) and is aligned in each diaphragm position with the focus (1) of the X-ray tube. <IMAGE>
