Abstract
An apparatus for positioning and marking a patient at a diagnostic apparatus, for example before and after being scanned in a computer tomograph, comprising at least four line lasers adapted to be displaced along an axis, two of said line lasers being arranged above the patient lying upon a displaceable bed so as to project a sagittal line and a transversal line onto the body of the patient and two of said line lasers being arranged laterally of the bed so as to project a line along the body axis laterally onto the body, numerically controlled drives for said line lasers for adjustment thereof transversely to the respective projected lines, position control means for said drives, and manually operable input means for said control means for entering coordinates related to the position and extent of an area to be irradiated and determined by the computer tomograph.
