Abstract
The invention relates to a method for registering a patient data set obtained by an imaging process in camera navigation-supported surgical operations, comprising the following steps:producing a patient data set by means of a tomographic scan or an imaging process for the body of the patient or a part thereof,applying at least one marker array, identifiable and trackable in the navigation system, to at least one solid body structure, preferably a bone structure, after the patient has been brought into an operating room and during treatment, in particular after the area to be treated has been exposed,producing one or more x-ray images of the area to be treated by means of an x-ray unit, the spatial position of said images in the navigation system being determined,updating, by means of a computer-assisted assignment, the register of the patient data set with the positional data obtained from the x-ray image, anddetecting and re-registering movements or relative movements in the area to be treated by tracking said marker array(s) in the navigation system.
