    Patent number: 10716521
    Abstract: The current invention relates to a patient support table, comprising a frame that is mounted to the floor, an upright column with a table top support system and mounted to the frame and supporting a table top that is movable longitudinally with respect to the column and to accommodate a person. The patient table further comprises a tilt actuator and a control device to control the at least one tilt actuator, and comprising an inclinometer, a data storage and a processing unit that in use compares data from the inclinometer with data from the data storage. The control device comprises a force sensor to determine a load supported by the table top and/or a position sensor to determine the longitudinal position of the table top with respect to a reference, wherein the control device in use calculates a set point for the at least one tilt actuator and actuates the tilt actuator to move or maintain the table top to the set tilted position.
