X-ray examination apparatus, comprising an examination table which can be swivelled around a horizontal axis

摘要

In an X-ray examination apparatus comprising an examination table which can be tilted around a horizontal shaft, a mechanical coupling between the X-ray source and the image section is replaced by a coupling between the table and the image section, the image intensifier being connected to a ceiling-mounted stand. Motors for vertical and horizontal displacement and rotation are provided. The three motors are controlled by an arithmetic device so that when the examination table is swivelled, the location and position of the image section with respect to the examination table is not changed. In an examination apparatus of this kind, the construction of the examination table may be substantially lighter, because the image section and the counterweights need not be supported by the examination table. The image section can be displaced in a larger area perpendicular to the top of the patient examination table and the patient can be introduced into the apparatus from the left as well as from the right.
