摘要：
A method for displaying a position of a medical device, such as a catheter, during insertion thereof into a patient. In one example embodiment, the method includes obtaining a first set of detected position data relating to a location marker, such as a permanent magnet, then determining a possible first position thereof. A first confidence level relating to a match between the first set of detected position data and a first set of predicted position data is assigned. A determination is made whether the first confidence level meets or exceeds a first threshold. If the first confidence level meets or exceeds the first threshold, a determination is then made whether the first position of the location marker is within a first detection zone. If the first position of the location marker is within the first detection zone, the first position of the location marker is displayed.
