ABSTRACT:
A wall-mounted x-ray system (10) includes a pair of parallel, spaced tracks (11, 12) mounted on a wall and capable of receiving, through either of their open ends (35, 36), traveller assemblies (13, 14). One traveller assembly (13) carries an x-ray tube (18) for the x-ray source and the other traveller assembly (14) carries x-ray receiving and patient locating equipment (16). The traveller assemblies (13, 14) are moveable on the tracks (11, 12), which movement is assisted by handles (42). Handles (42) are threaded into traveller assemblies (13, 14) and when the desired position along tracks (11, 12) is reached, by tightening the handles (42) the tracks (11, 12) are engaged to hold the traveller assemblies (13, 14) in place. Traveller assembly (14) is first properly positioned relative to the patient and then traveller assembly (13) is aligned with traveller assembly (14) by use of an optical transmitter (45) carried by traveller assembly (13) and a receiving target (47) carried by traveller assembly (14).
