The X-ray examination apparatus has a stand (1) with at least one pedestal (3) and a holder (5) for a carrier (6). The holder (5) is rotatable about an horizontal axis and is connected to the pedestal (3). An X-ray tube (7) and a receptor (8) are fastened to the carrier arm (6). An arm (9) connects the stand (1) to a fastening device (11). One end of the arm (9) rotates on the fastening device (11). An examination table (2) can be displaced at least along a central line. The fastening device (11) is so placed that its axis (10) lies outside the central line of the table (2). The other end of the arm (9) is rotatably connected to a vertical axis (13) on the pedestal (3). As the arm (9) rotates about the axis (10) of the fastening device (11), the stand (1) rotates about the axis (10) of the pedestal (3) such that the central line (21) of the X-ray tube (7) and the receptor (8) cuts the central line (18) of the table (2) in at least two angular positions. In the first angular position, the stand (1), when viewed from above, is aligned with the central line (18) of the table (2). In the second position, it forms an angle with the central line of the table (2). |
