Computed tomography unit and method for a computed tomography unit having at least one marking device for the positionally accurate marking of an intervention position by way of a laser beam on an object to be examined

摘要

A computed tomography unit and a method are disclosed, for a computed tomography unit having at least one marking device for the positionally accurate marking of an intervention position by way of a laser beam on an object to be examined. The at least one marking device is assigned to a rotary frame of the computed tomography unit and is arranged directly in a recording plane of a recording system. As such, a positionally accurate marking of an intervention position with the aid of simple devices/methods is possible without a large numerical outlay, particularly even during operation of the computed tomography unit, that is say during a rotational movement of the rotary frame.
