The invention relates to an X-ray diagnosis apparatus for mammography having an X-ray tube (3) which is rotatable via a horizontal shaft (4) about a bearing (5) arranged in a stand (1), and at least two cassette holders (9, 10) which can be brought into a recording position when required. The cassette holders (9, 10) are pivotable about the horizontal shaft (4) in such a way that the cassette holder (9) is in a stop position when the other cassette holder (10) is brought into the recording position. In order to provide an X-ray diagnosis apparatus of the type mentioned which has an exchangeable arrangement for the cassette holders (9, 10) and which is comparatively small and easy to handle, it is proposed, according to the invention, that the axis of rotation (6) of the horizontal shaft (4) be arranged so that its axis is approximately aligned with the middle of the object (7) to be examined and that the cassette holders (9, 10) be fixed in a holder (8) which is rotatably mounted on the horizontal shaft (4), such that the cassette holder (9) is in a stop position behind the X-ray tube (3), as seen from the object (7) to be examined, when the other cassette holder (10) is brought into the recording position, rotation of the holder (8) about the shaft (4) being such that the cassette holders (9, 10) are each at approximately the same distance from the axis of rotation (6) of the horizontal shaft (4) when they are in the recording position. <IMAGE> |
