REAL-TIME DISPLAY OF VASCULATURE VIEWS FOR OPTIMAL DEVICE NAVIGATION Russian patent published in 2017 - IPC A61B6/00 A61B6/12 

FIELD: medicine.

SUBSTANCE: device for assisting in moving a device in a network of tubular structures comprises an input module for receiving a current reference projection image obtained in a first projection direction while the device is placed in a network of tubular structures. The projection image in the display shows the fingerprint of the device, a processor configured to use the current position in the fingerprint image and the network model in order to retrieve, without using the received 3D image data of the network, an auxiliary projection image from a sequence of previously obtained two-dimensional projection images, The auxiliary image when displayed shows at least a partial print of the network. Such extracted auxiliary image provides a view along the second projection direction for the network in the area under investigation and the graphic display driver. A method of assisting in moving is carried out by means of the device. An X-ray visualization system for assisting in the movement of the device in a network of tubular structures comprises an X-ray imaging module, a database, a device for assisting in the movement of the device. The projected images used in it are extracted from the database, the screen and the machine-readable medium.

EFFECT: expansion of the arsenal of technical means of movement in the network of tubular structures.
