Medical apparatus includes a patient table (7) with a table support (9) and a table top (11) which is movable at least in its longitudinal direction relative to the table support, there being provided a first drive mechanism (21) to assist said movement, if desired; the table top can be locked relative to the table support by means of a locking mechanism (23). The apparatus comprises a common control member (43) for moving the table top (11) in the longitudinal direction and for operating the first drive mechanism (21) and the locking mechanism (23). The control member comprises a link rod (57) which is movable in its longitudinal direction and which cooperates with a switch (67) for operating the locking mechanism, and also comprises a control element (71) which is movable transversely of the longitudinal direction of the link rod and which cooperates with a sensor (73) which supplies an output signal for control of the drive mechanism. The link rod (57) and the control element (71) are movable by means of a common control knob (59) whereby the table top (11) can be moved also without assistance from the first drive mechanism (21). Consequently, control of the movements of the table top (11) is very simple and orderly.
