摘要：
A method for simulating the bend shape of a catheter (20) includes providing at least two sensor elements (24,25) in the catheter (20), and said sensor elements (24,25) traverse magnetic line of force to generate induced current. Space information of the sensor elements (24,25) is extracted from the induced current information, and the bend shape of the catheter (20) is calculated according to aforementioned space information in combination with characteristic information of the catheter (20). A catheter (20) includes a catheter body (22), at least two magnetic sensors (24,25), a signal extracting device (40), and a simulating and processing device (50).
