Abstract
A method for assisting navigation of an endoscopic device using a controller with the aid of a digital image data record of an imaging examination modality is provided. The digital image data record describes an image of an object to be examined with the aid of the endoscopic device in a cavity element. A digital two-dimensional or multi-dimensional model of the object to be examined is determined based on the image data record. An operating action that predetermines a relative location of a sensor of the endoscopic device in relation to the object based on the model is received. The model is registered with the endoscopic device and/or a digital endoscopic data record supplied by the endoscopic device. An initial location of the sensor is compared with the predetermined location, and a navigation signal for navigating the endoscopic device is generated taking into account the predetermined relative location.
