Patent ID: 11628014

Abstract:
The invention relates to a system for assisting in navigating a medical device (1) in a region of a patient body, such as a cardiac chamber. The system comprises a unit (5) for providing a three-dimensional model of the region and an ultrasound probe (2) for acquiring image signals of the region of the patient body. At least one an ultrasound sensor (6) is attached to the medical device (1) for sensing ultrasound signals emitted by the 5 ultrasound probe (2) and a tracking unit (7) determines a relative position of the at last one ultrasound sensor (6) with respect to the live images and/or the ultrasound probe (2) on the basis of the sensed ultrasound signals. Further, a mapping unit (8) maps the determined relative position of the at least one ultrasound sensor (6) onto the model to generate a visualization of region of the patient body.
