System and method intended to follow the movement of an instrument during the replacement of a heart valve percutaneous

摘要

A system (100) and a method (200) in order to follow the movement of an instrument (105) during the replacement of a valve, percutaneous cardiac of a subject (115) are made. The system (100) includes an imaging system (120), a navigation system (125) in order to follow the movement of the instrument (105) in the subject (115) and illustrating a representation of a position of the instrument (105) in the spatial relationship with the images obtained by the imaging system (120), and a control device (130). The control device (130) is used to identify an access path from a series of access paths (250, 300) to move the instrument (105) in the subject (115) during the replacement of the valve, percutaneous cardiac, to identify a sequence of patterns (400 and 450) illustrating the access path selected from among the plurality of access paths (250, 300) for detecting the position of the instrument (105) in the field of one of the models (455, 460, 465, 470) of the sequence (400 and 450), and to create a display (145) comprising a representation of the instrument (105) with the model (460) present in the field.
