Abstract
An OSS foreshortening detection system employing an interventional device (40) including a OSS sensor (20) having shape nodes for generating shape sensing data informative of a shape of OSS sensor (20). The system further employs a OSS foreshortening detection device (80) including a OSS shape controller (90) for reconstructing a shape of a portion/entirety of interventional device (40) derived from a generation of the shape sensing data by OSS sensor (20). Device (80) further includes a OSS foreshortening controller (100) for monitoring any foreshortening of the interventional device (40) within an image of the interventional device (40) including the OSS foreshortening controller (100) detecting a location of any occurrence of a foreshortening of the interventional device (40) within the image of interventional device (40) derived from the reconstruction of the shape of the portion/entirety of interventional device (40) by the OSS shape controller (90).
