Abstract
Abstract The invention relates to an X-ray tomograph in which the X-ray tube can perform movements which are independent of each other in two directions at right angles to each other. The X-ray tube in a first support can be moved in the transverse direction which is connected to a second support extending in the longitudinal direction which in its main direction is journalled so as to be movable in a stand connected to the floor.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
207 words
An X-ray tomograph comprising: X-ray table means for horizontally supporting a patient undergoing examination above a floor; X-ray picture recording means disposed beneath the table means; a vertical support column having a first end which is rigidly attached to the floor near the table means and a second end which extends from the floor above the height of the table means; angular guide means attached to the second end of the column; first horizontal support means journalled in said guide means for horizontal motion parallel to a longitudinal direction of the table means; second horizontal support means affixed to one end of the first horizontal support means; carriage means journalled in the second support means for horizontal motion perpendicular to the longitudinal direction of the table means; an X-ray tube connected to the carriage means for projecting X-rays through the table means to the recording means; a coupling rod connecting the carriage means to the recording means to produce coordinated motion of the carriage means and the recording means; and motor means for horizontally displacing the first support parallel to the longitudinal direction with respect to the guide means and for horizontally displacing the carriage, perpendicular to the longitudinal direction, with respect to the second support means.
Claim 2
Dependent Claim
207 words
An X-ray tomograph comprising: X-ray table means for horizontally supporting a patient undergoing examination above a floor; X-ray picture recording means disposed beneath the table means; a vertical support column having a first end which is rigidly attached to the floor near the table means and a second end which extends from the floor above the height of the table means; angular guide means attached to the second end of the column; first horizontal support means journalled in said guide means for horizontal motion parallel to a longitudinal direction of the table means; second horizontal support means affixed to one end of the first horizontal support means; carriage means journalled in the second support means for horizontal motion perpendicular to the longitudinal direction of the table means; an X-ray tube connected to the carriage means for projecting X-rays through the table means to the recording means; a coupling rod connecting the carriage means to the recording means to produce coordinated motion of the carriage means and the recording means; and motor means for horizontally displacing the first support parallel to the longitudinal direction with respect to the guide means and for horizontally displacing the carriage, perpendicular to the longitudinal direction, with respect to the second support means.
