An X-ray stand comprising a generally arcuate swing arm (10) on which is provided an X-ray tube (15) in a stationary housing (14) and an X-ray detector (16). The detector (16) is hingedly mounted via a smaller arm (20) to the swing arm (10), so as to enable the smaller arm (20) to pivot relative to the upper end of the swing arm (10). The detector plate (16) is mounted to the free end of the smaller arm (20) by means of a joint (22) which enables the detector plate (16) to be pivoted relative to the smaller arm (20). In addition, the X-ray tube (15) is mounted on a pivotal carriage (15a) within the housing (14) such that it can be relatively tilted, and the carriage (15a) in or on which the X-ray tube (15) is provided is mounted within the housing (14) on a sliding mechanism (30) which permits the selective rotational movement of the X-ray tube (15) within the housing (14). Thus, because the detector (16) and X-ray tube (15) can be moved in a substantially vertical direction relative to the patient (24) the maximum achievable jaw size (28) is increased without a significant increase in the size of the stand. |
