摘要： A method displays a representation of the tip of a medical device located within a body region of interest of the body of a patient, on an image of the body region of interest, the image being acquired by an image detector of a moving imager. The method includes the procedures of acquiring a medical positioning system (MPS) sensor image of an MPS sensor, determining a set of intrinsic and extrinsic parameters, determining two-dimensional optical coordinates of the tip of the medical device, superimposing the representation of the tip of the medical device, on the image of the body region of interest, and displaying the representation of the tip of the medical device superimposed on the image of the body region of interest.
