  • Publication number: 20200197106
    Abstract: A method and system for automatic landmark registration and registration using trajectory information and shape sensing during an endoscopic procedure, such as bronchoscopy, are described herein. A segmentation centerline of airways of a lung may be generated based on a pre-operative computed tomography (CT) image of the lung. Landmarks may be automatically detected on the segmentation centerline corresponding to bifurcations in the airways of the lung. A location data point cloud of locations of a catheter through the airways of the lung during navigation may be generated. A bounding volume of the airways of the lung may be generated and a bounding volume centerline may be detected. Landmarks may be detected on the bounding volume centerline for the same bifurcations. Then, the two sets of landmarks may be mapped as part of registration. The trajectory information with shape sensing may be used to provide non-rigid or fine registration.

  • Publication number: 20190388154
    Abstract: A method includes receiving an anatomical mapping that includes multiple measurements acquired at multiple respective locations within an organ of a patient. An estimated surface of the organ is computed based on the measurements. A three-dimensional (3D) shell of the organ, which extends inwards from the estimated surface of the organ and has a predefined thickness, is defined. A quality of the anatomical mapping is estimated based on the measurements whose locations fall within the 3D shell.

  • Patent number: 10492867
    Abstract: A method, consisting of receiving a computerized tomography scan of at least a part of a body of a patient, and identifying voxels of the scan that correspond to regions in the body that are traversable by a probe inserted therein. The method also includes displaying the scan on a screen and marking thereon selected start and termination points for the probe. A processor finds a path from the start point to the termination point consisting of a connected set of the identified voxels. The processor also uses the scan to generate a representation of an external surface of the body and displays the representation on the screen. The processor then renders an area of the external surface surrounding the path locally transparent in the displayed representation, so as to make visible on the screen an internal structure of the body in a vicinity of the path.

  • Patent number: 10452263
    Abstract: A method of registering a patient face and using it as a touchpad interface is provided. The method includes steps of acquiring a three-dimensional anatomical image of a patient face, identifying multiple anatomical points at the predefined locations on the patient face in a first coordinate system and assigning at least one function to at least one predefined location, receiving multiple positions in a second coordinate system at the respective predefined locations on the patient face, registering the first and second coordinate systems, by correlating between the positions and the respective anatomical points on the patient face, triggering a command corresponding to the at least one assigned function and communicating the command to an electronic device. A system for registering a patient face by the method is described.

  • Publication number: 20190314032
    Abstract: A method includes inserting into a patient organ a catheter including a position sensor, a device and a handle. The position sensor is attached to a distal end of the catheter. The device is movable along the catheter. The handle includes a control for navigating the device along the catheter to a target location in the patient organ. Based on a location of the position sensor, a target position of the control on the handle that corresponds to the target location of the device is estimated. A marker is set to mark the target position of the control on the handle, and the device is navigated to the target location by setting the control to the marker.

  • Publication number: 20190142521
    Abstract: An apparatus, including a magnetic field generator, a first magnetic field sensor configured for attachment to a proximal end of a surgical tool configured for insertion into a body, and a calibration device that includes a second magnetic field sensor and a proximity sensor, wherein the field sensors generate respective location signals responsive to a magnetic field emanating from the generator and traversing the field sensors. The apparatus includes a control unit, which receives the signals from all the sensors, extracts respective location and orientation coordinates of the field sensors based on the signals, computes a conversion relation between the coordinates of the first sensor and a distal end of the tool that is brought into contact with the calibration device, and subsequently applies the conversion relation, together with the coordinates of the first sensor, in providing a visual indication of a location of the distal end inside the body.

  • Patent number: 10242548
    Abstract: A conduit puncture alert method and apparatus are provided for a medical instrument having a flexible conduit through which a medical procedure is performed. In one embodiment, the flexible conduit is inserted into a subject. A highest degree of curvature of the conduit within the subject is sensed. A warning signal is then provided upon a condition that a curvature is sensed that exceeds a predetermined limit reflective of a maximum curvature permissible for a selected tool to be inserted through the conduit while avoiding puncturing of the conduit by the selected tool. For example, the method can be conducted with respect to a bronchoscope during a bronchoscopic procedure where a needle tool is to be used and the warning is given with respect to that tool when a conduit curvature is sensed that exceeds a predetermined limit determined with respect to the needle tool.

  • Publication number: 20190069953
    Abstract: Methods and apparatus for enhancing bronchial airways representations using vascular morphology. A representation of bronchial airways of a subject and a representation of a corresponding vascular network are obtained and may be stored in a memory. In the bronchial airways representation, termini of airways are identified where portions of the airways are not included in the representation though they are in fact continuous airways in the subject. In the vascular network representation, vessel portions corresponding to unrepresented airway portions between first and second identified airway termini are identified. An enhanced bronchial airways representation is produced that reflects an airway extending between the termini. The enhanced bronchial airways representation can be displayed on a monitor of a medical apparatus to facilitate a bronchoscopic procedure.

  • Publication number: 20190046272
    Abstract: A method, including receiving a computerized tomography (CT) image of voxels of a subject's head, and analyzing the image to identify respective locations of the subject's eyes in the image, so defining a first line segment joining the respective locations. The method includes identifying a voxel subset overlaying bony sections of the head, lying on a second line segment parallel to the first line segment and on a third line segment orthogonal to the first line segment. A magnetic tracking system configured to measure positions on the subject's head is activated, and a probe, operative in the system, is positioned in proximity to the bony sections to measure positions of a surface of the head overlaying the bony sections. A correspondence between the positions and the voxel subset is formed, and a registration between the CT image and the magnetic tracking system is generated in response to the correspondence.
