摘要：
A system and method for determining the length of a non-shape-sensed interventional device (102) which includes a shape-sensed guidewire (106) that is received in the lumen (103) of the device. A hub (107) is configured to secure a position of the shape-sensed guidewire and interventional device. A registration module (124) is configured to register a position of the distal tip (117) of the non-shape-sensed interventional device to a position of the shape-sensed guidewire. A determination module (126) determines the length of the non-shape-sensed interventional device using a known position of the device in the hub and the position of the distal tip of the device. The system includes a detection module (146) that receives curvature data from the shape-sensed guidewire and is configured to determine the state of the shape-sensed guidewire with respect to an interventional device.
