ultraschallbasiertes positioning system and method for an invasive freihandvorrichtung

摘要

in one embodiment includes a interventionelles control procedure (42) generating a ultraschallbildes (100) of the relevant anatomical area (104, 106, 108).the method involves the superposition of the ultraschallbildes with an optical display (34, 110, 112, 114, 118, 120, 124, 126) of at least one of the projection of a position of an interventional device (34), the verlaufsbahn interventional device (34), and egg a positionthe interventional device (34), a ultraschallbildebene (102) cut. the interventional control procedure (42) also includes the dynamic alteration of one aspect of the superposed optical display (34, 110, 112, 114, 118, 120, 124, 126) during an interventional procedure.the dynamic modification includes modification of a dynamic display (114, 118, 120) of a diagonal to the image plane (102) arranged verlaufsbahn of the interventional instrument (34) or an interface (110, 124, 126) of the verlaufsbahn of the interventional instrument (34) with the bi ldebene (102).
