Abstract
An apparatus for positioning and marking a patient at a diagnostic apparatus, for example prior and after transillumination in a computer tomograph, comprising a plurality of line lasers which project lines in planes perpendicular to each other for alignment with a patient body zone to be irradiated and for marking thereof, the improvement of which comprises a first line laser being fixed to a support member which is mounted so as to be rotatable about an axis adapted to be aligned substantially to a central axis of the diagnostic apparatus, e.g. computer tomograph, the light beam of the eccentrically positioned line laser being in a plane extending through a Z-axis, which plane is perpendicular to the bed between said diagnostic apparatus and said support member when the support member is in a zero position, said support member being adapted to be driven by a numerically controlled drive and control means being provided for displacing said support member in response to control data corresponding to coordinates of a tumor determined by said diagnostic apparatus.
