20080207997 | METHOD AND APPARATUS FOR CONTINUOUS GUIDANCE OF ENDOSCOPY - 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. | 08-28-2008 |
20100280365 | GUIDANCE METHOD BASED ON 3D-2D POSE ESTIMATION AND 3D-CT REGISTRATION WITH APPLICATION TO LIVE BRONCHOSCOPY - A method provides guidance to the physician during a live bronchoscopy or other endoscopic procedures. The 3D motion of the bronchoscope is estimated using a fast coarse tracking step followed by a fine registration step. The tracking is based on finding a set of corresponding feature points across a plurality of consecutive bronchoscopic video frames, then estimating for the new pose of the bronchoscope. In the preferred embodiment the pose estimation is based on linearization of the rotation matrix. By giving a set of corresponding points across the current bronchoscopic video image, and the CT-based virtual image as an input, the same method can also be used for manual registration. The fine registration step is preferably a gradient-based Gauss-Newton method that maximizes the correlation between the bronchoscopic video image and the CT-based virtual image. The continuous guidance is provided by estimating the 3D motion of the bronchoscope in a loop. Since depth-map information is available, tracking can be done by solving a 3D-2D pose estimation problem. A 3D-2D pose estimation problem is more constrained than a 2D-2D pose estimation problem and does not suffer from the limitations associated with computing an essential matrix. The use of correlation-based cost, instead of mutual information as a registration cost, makes it simpler to use gradient-based methods for registration. | 11-04-2010 |
20110128352 | FAST 3D-2D IMAGE REGISTRATION METHOD WITH APPLICATION TO CONTINUOUSLY GUIDED ENDOSCOPY - A novel framework for fast and continuous registration between two imaging modalities is disclosed. The approach makes it possible to completely determine the rigid transformation between multiple sources at real-time or near real-time frame-rates in order to localize the cameras and register the two sources. A disclosed example includes computing or capturing a set of reference images within a known environment, complete with corresponding depth maps and image gradients. The collection of these images and depth maps constitutes the reference source. The second source is a real-time or near-real time source which may include a live video feed. Given one frame from this video feed, and starting from an initial guess of viewpoint, the real-time video frame is warped to the nearest viewing site of the reference source. An image difference is computed between the warped video frame and the reference image. The viewpoint is updated via a Gauss-Newton parameter update and certain of the steps are repeated for each frame until the viewpoint converges or the next video frame becomes available. The final viewpoint gives an estimate of the relative rotation and translation between the camera at that particular video frame and the reference source. The invention has far-reaching applications, particularly in the field of assisted endoscopy, including bronchoscopy and colonoscopy. Other applications include aerial and ground-based navigation. | 06-02-2011 |

20130070286 | METHODS AND SYSTEMS FOR LOAD LEVELING IN A PRINT SHOP - A method and system for managing print shop workflow determines whether variations in print shop workflow may be reduced by shifting one or more customers' scheduled orders to different time periods. By shifting an order from one time period to another, the system may reduce variability in demand levels over time, thus helping increase overall system efficiency. To do this, one or more customers are selected as candidates for print shop order rescheduling. The system identifies customer orders that, if moved to other time periods, will most reduce demand level variations. A user may accept the system's recommendations, or the system may present a user with several alternative load leveling options for selection. The system may then cause the orders to be printed based on the load leveling proposal and the user's selection. | 03-21-2013 |

20110319823 | TUBE MEASUREMENT TECHNIQUE USING LINEAR ACTUATOR AND PRESSURE SENSOR - An infusion pump uses sensors, movable members and a control unit to determine tubing thickness in a tube-loading section of the pump. The infusion pump utilizes sensors, such as a pressure sensor, to record forces imparted by a tube undergoing no pressure, a single pressure, or a pressure sweep, to determine thickness. Using these values, the tubing wall thickness can be determined. The infusion pump can also compress a tube using a movable member of the pump and records the distance traveled by the movable member to compress fully the tube. Using this distance, the tubing wall thickness can be determined. | 12-29-2011 |

20100103781 | TIME SYNCHRONIZATION IN CLUSTER SYSTEMS - Techniques are described herein for synchronizing cluster time. According to one technique, a master node is appointed in a cluster. Other “slave” nodes periodically synchronize their clocks with the master node. To synchronize its clock with the master node, a slave node sends a timestamped message to the master node, which also timestamps the message and sends the message back to the slave node, which then timestamps the message again. Based on the timestamps, the slave node is able to determine the difference between the master node's clock's time and slave node's clock's time, compensating for the message travel time between master node and slave node. Depending on various circumstances, and based on the determined difference, the slave node adjusts its clock so that the time indicated by the slave node's clock at least begins to approach more closely the time indicated by the master node's clock. | 04-29-2010 |

20080281938 | Selecting a master node in a multi-node computer system - Selecting a master node in a multi-node computer system is described. Each node of the multi-node computer system selects a timeout value (e.g., randomly). Each node starts a timer, which is set to expire at the selected timeout value of its corresponding node. The node with the timer that expires earliest broadcasts an election message to the other nodes of the multi-node computer system, which informs the other nodes that the broadcasting node is a candidate for mastership over the multi-node computer system. The other nodes respond to the election message upon receiving it. In the absence of a refusal message from one or more of the other nodes, the candidate is established as master node in the multi-node computer system and wherein the other nodes function as slave nodes therein. | 11-13-2008 |
