    Abstract: An ultrasound device (10) comprises a probe (12) including a tube (14) sized for in vivo insertion into a patient and an ultrasound transducer (18) disposed at a distal end (16) of the tube. A camera (20) is mounted at the distal end of the tube in a spatial relationship to the ultrasound transducer. At least one electronic processor (28) is programmed to: control the ultrasound transducer and the camera to acquire ultrasound images (19) and camera images (21) respectively while the ultrasound transducer is disposed in vivo; construct keyframes (36) during in vivo movement of the ultrasound transducer, each keyframe representing an in vivo position of the ultrasound transducer and including at least ultrasound image features (38) extracted from at least one of the ultrasound images acquired at the in vivo position of the ultrasound transducer and camera image features (40) extracted from at least one of the camera images acquired at the in vivo position of the ultrasound transducer; generate a navigation map (45) of the in vivo movement of the ultrasound transducer comprising the keyframes; and output navigational guidance (49) based on comparison of current ultrasound and camera images acquired by the ultrasound transducer and camera with the navigation map.

    Abstract: An OSS guiding and monitoring system employs an interventional device (40) including an integration of a OSS sensor (20) and one or more interventional tools (30), the OSS sensor (20) for generating shape sensing data informative of a shape of the OSS sensor (20) as the interventional device (40) is navigated within an anatomical region. The OSS guiding and monitoring system further employs an OSS guiding controller (90) for controlling a reconstruction of a shape of the interventional device (40) within the anatomical region responsive to a generation of the shape sensing data by the OSS sensor (20), and an OSS monitoring controller (100) for controlling a monitoring of a degree of folding and/or a degree of twisting of the interventional device (40) within the anatomical region.

    Abstract: A controller (122) includes a memory (12220) that stores instructions and a processor (12210) that executes the instructions. When executed, the instructions cause the controller (122) to implement a process that includes obtaining (S405) pre-operative imagery of the tissue in a first modality, registering (S425) the pre-operative imagery of the tissue in the first modality with a set of sensors (195-199) adhered to the tissue, and receiving (S435), from the set of sensors (195-199), sets of electronic signals for positions of the set of sensors (195-199). The process also includes computing (S440) geometry of the positions of the set of sensors (195-199) for each set of the sets of electronic signals and computing (S450) movement of the set of sensors (195-199) based on changes in the geometry of the positions of the set of sensors (195-199) between sets of electronic signals from the set of sensors (195-199). The pre-operative imagery is updated to reflect changes in the tissue based on movement of the set of sensors (195-199).

    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).

    Abstract: An ultrasound device (10) includes a probe (12) including a tube (14) sized for insertion into a patient and an ultrasound transducer (18) disposed at a distal end (16) of the tube. A camera (20) is mounted at the distal end of the tube in a fixed spatial relationship to the ultrasound transducer. At least one electronic processor (28) is programmed to: control the ultrasound transducer and the camera to acquire ultrasound images (19) and camera images (21) respectively while the ultrasound transducer is disposed in vivo inside the patient; and construct a keyframe (36) representative of an in vivo position of the ultrasound transducer including at least ultrasound image features (38) extracted from at least one of the ultrasound images acquired at the in vivo position of the ultrasound transducer and camera image features (40) extracted from one of the camera images acquired at the in vivo position of the ultrasound transducer.

    Abstract: Systems and methods are provided for registering a shape sensing device, such as an optical shape sensing (OSS) device, with a previously obtained three-dimensional (3D) representation of a region of interest, the shape sensing device including an outer body for maneuvering through a passage in the region of interest and a force sensing region integrated with the outer body. The method determines multiple points at which an end of the outer body contacts a surface of an object in the region of interest, based on forces exerted on the end when contacting the surface and detected by the force sensing region; and registering the determined points with points in the 3D representation of the region of interest so that the registered points are in a common space.
