Appl. No.:

12/018953

Inventors:

William E. Higgins - State College PA, US
Jason D. Gibbs - State College PA, US

Assignee:

The Penn State Research Foundation - University Park PA

International Classification:

A61B 6/03

US Classification:

600425

Abstract:

Methods and apparatus assist in planning routes through hollow, branching organs in patients to optimize subsequent endoscopic procedures. Information is provided about the organ and a follow-on endoscopic procedure associated with the organ. The most appropriate navigable route or routes to a target region of interest (ROI) within the organ are then identified given anatomical, endoscopic-device, or procedure-specific constraints derived from the information provided. The method may include the step of modifying the viewing direction at each site along a route to give physically meaningful navigation directions or to reflect the requirements of a follow-on live endoscopic procedure. An existing route may further be extended, if necessary, to an ROI beyond the organ. The information provided may include anatomical constraints that define locations or organs to avoid; anatomical constraints that confine the route within specific geometric locations; or a metric for selecting the most appropriate route. For example, the metric may define the closest route to the ROI such that the route satisfies all applicable anatomical, device, and procedural constraints.

International Classification:

A61B 1/01

US Classification:

600114

Abstract:

Methods and apparatus provide continuous guidance of endoscopy during a live procedure. A data-set based on 3D image data is pre-computed including reference information representative of a predefined route through a body organ to a final destination. A plurality of live real endoscopic (RE) images are displayed as an operator maneuvers an endoscope within the body organ. A registration and tracking algorithm registers the data-set to one or more of the RE images and continuously maintains the registration as the endoscope is locally maneuvered. Additional information related to the final destination is then presented enabling the endoscope operator to decide on a final maneuver for the procedure. The reference information may include 3D organ surfaces, 3D routes through an organ system, or 3D regions of interest (ROIs), as well as a virtual endoscopic (VE) image generated from the precomputed data-set. The preferred method includes the step of superimposing one or both of the 3D routes and ROIs on one or both of the RE and VE images. The 3D organ surfaces and routes may correspond to the surfaces and paths of a tracheobronchial airway tree extracted, for example, from 3D MDCT images of the chest.

International Classification:

A61B 1/012

US Classification:

600104, 600117

Abstract:

Endoscopic poses are used to indicate the exact location and direction in which a physician must orient the endoscope to sample a region of interest (ROI) in an airway tree or other luminal structure. Using a patient-specific model of the anatomy derived from a 3D MDCT image, poses are chosen to be realizable given the physical characteristics of the endoscope and the relative geometry of the patient's airways and the ROI. To help ensure the safety of the patient, the calculations also account for obstacles such as the aorta and pulmonary arteries, precluding the puncture of these sensitive blood vessels. A real-time visualization system conveys the calculated pose orientation and the quality of any arbitrary bronchoscopic pose orientation. A suggested pose orientation is represented as an icon within a virtual rendering of the patient's airway tree or other structure. The location and orientation of the icon indicates the suggested pose orientation to which the physician should align during the procedure.

International Classification:

G06K 9/00
G06T 15/00

US Classification:

382131, 345419

Abstract:

This invention relates generally to medical imaging and, in particular, to a method and system for reconstructing a model path through a branched tubular organ. Novel methodologies and systems segment and define accurate endoluminal surfaces in airway trees, including small peripheral bronchi. An automatic algorithm is described that searches the entire lung volume for airway branches and poses airway-tree segmentation as a global graph-theoretic optimization problem. A suite of interactive segmentation tools for cleaning and extending critical areas of the automatically segmented result is disclosed. A model path is reconstructed through the airway tree.

International Classification:

G06G 7/60

US Classification:

703 11

Abstract:

A system and method are described for determining candidate fiducial marker locations in the vicinity of a lesion. Imaging information and data are input or received by the system and candidate marker locations are calculated and displayed to the physician. Additionally, interactive feedback may be provided to the physician for manually selected or identified sites. The physician may thus receive automatic real time feedback for a candidate fiducial marker location and adjust or accept a constellation of fiducial marker locations. 3D renderings of the airway tree, lesion, and marker constellations may be displayed.

International Classification:

US Classification:

600117

Abstract:

A technician-free strategy enables real-time guidance of bronchoscopy. The approach uses measurements of the bronchoscope's movement to predict its position in 3D virtual space. To achieve this, a bronchoscope model, defining the device's shape in the airway tree to a given point p, provides an insertion depth to p. In real time, the invention compares an observed bronchoscope insertion depth and roll angle, measured by an optical sensor, to precalculated insertion depths along a predefined route in the virtual airway tree to predict a bronchoscope's location and orientation.

International Classification:

US Classification:

382131, 382128

Abstract:

A medical analysis method for estimating a motion vector field of the magnitude and direction of local motion of lung tissue of a subject is described. In one embodiment a first 3D image data set of the lung and a second 3D image data set is obtained. The first and second 3D image data sets correspond to images obtained during inspiration and expiration respectively. A rigid registration is performed to align the 3D image data sets with one another. A deformable registration is performed to match the 3D image data sets with one another. A motion vector field of the magnitude and direction of local motion of lung tissue is estimated based on the deforming step. The motion vector field may be computed prior to treatment to assist with planning a treatment as well as subsequent to a treatment to gauge efficacy of a treatment. Results may be displayed to highlight.

International Classification:

US Classification:

600425

Abstract:

A method and system for assisting a physician track a surgical device in a body organ of a subject during a procedure includes fluoroscopic based registration, tracking, and optimizing a fluoroscopy position. An initial registration step includes receiving a 3D image data of a subject in a first body position, receiving a real time fluoroscopy image data, and estimating a deformation model or field to match points in the real time fluoro image with a corresponding point in the 3D model. A tracking step includes computing the 3D location of the surgical device and displaying the surgical device and the 3D model of the body organ in a fused arrangement. Optimizing the fluoroscope camera pose includes computing a candidate camera pose to assist the surgeon to track a surgical device based on features of the surgical device, position of the patient, and mechanical properties or constraints of the fluoroscope.
