Patent number: 11026750Abstract: An apparatus and method for surgical tracking comprises an imaging device that generates an image of a tissue volume; an electromagnetic (EM) sensor that creates a reference frame for EM tracking in three dimensions; at least one EM sensor adapted to be attached to the tissue to track local deformation and movement of the tissue volume; a processor that registers the image with the EM-tracked tissue volume and surgical tool in real time, and produces an output; and a feedback device that provides feedback about the location of the surgical tool relative to the tissue volume, based on the processor output. Embodiments are particularly useful in soft tissue, such as breast, where deformation before and during a procedure such as tumor resection complicate tracking of the tissue volume and a surgical tool.Type: GrantFiled: January 22, 2016Date of Patent: June 8, 2021Assignees: Queen's University at Kingston, Kingston Health Sciences CentreInventors: Gabor Fichtinger, Tamas Ungi, John F. Rudan, Andras Lasso, C. Jay Engel, Gabrielle Gauvin, Caitlin Yeo

Patent number: 11007015Abstract: Provided are apparatus and methods for tracking a volume of interest in three dimensions in real time, using fewer than 6 DOF tracking information together with an external 6 DOE coordinate system. The apparatus and methods described herein provide more accurate, smaller, and less expensive tracking systems than prior approaches based on full 6 DOF tracking comprising translation and full orientation information. Embodiments may be used in applications such as surgical navigation, gaming, robotics, motion capture, and training.Type: GrantFiled: January 29, 2019Date of Patent: May 18, 2021Assignee: Queen's University at KingstonInventors: Thomas Vaughan, Andras Lasso, Gabor Fichtinger, Tamas Ungi

Patent number: 9743912Abstract: An ultrasound calibration phantom comprises a portion including at least one fiducial structure having a selected geometric arrangement; a portion adapted for mechanical coupling of the ultrasound calibration phantom to a transrectal ultrasound (TRUS) stepper; and a guide for at least one surgical instrument, the guide being mechanically coupled to the fiducial structure and/or to the TRUS stepper at a selected pose relative to the fiducial structure. A calibration method uses the calibration phantom and provides automatic, intraoperative calibration of ultrasound imaging systems. The invention is useful in ultrasound-guided clinical procedures.Type: GrantFiled: October 31, 2013Date of Patent: August 29, 2017Assignee: QUEEN'S UNIVERSITY AT KINGSTONInventors: Gabor Fichtinger, Purang Abolmaesumi, Clif E.

Publication number: 20170065248Abstract: In one aspect the invention provides a reference device that enhances image-guided surgical interventions. The reference device is tracked by the imaging system and used to verify the accuracy of the intervention tool placement before and during the intervention. The reference device holds a reference sensor in a position aligned with patient anatomy, so that images are displayed in the correct orientation to the operator, aiding in target recognition and better navigation. Also provided are methods using the reference device and programmed computer media for implementing at least a part of the methods.Type: ApplicationFiled: August 12, 2016Publication date: March 9, 2017Inventors: Tamas Ungi, Andras Lasso, Gabor Fichtinger

Publication number: 20100315487Abstract: A method using an imaging device to define an acquisition geometry for 2D images of an observation region, a region for which there exists a 3D representation. 2D views of the 3D representation can be determined following the acquisition geometry of the imaging device for a plurality of viewing points, so that each acquired 2D image can be superimposed with any of this plurality of views. As a variant, in the 3D representation two views are determined corresponding to the viewing point at which the eye is positioned at the formation plane of the acquired image (front view and corresponds to the 2D image) and to the viewing point at which the eye is positioned at the focal point of the projective geometry (back view which is opposite to the viewing point of the 2D image).Type: ApplicationFiled: June 10, 2010Publication date: December 16, 2010Inventors: Florence Grassin, Yves Trousset, Elisabeth Soubelet, Cyril Riddell, Andras Lasso

Publication number: 20100130878Abstract: A system, apparatus and process for characterizing aspects of vascular scenarios is described, and includes an input module and a database. The system also includes access to a FSI solver. The FSI solver accepts information from the input module and the database, and uses the accepted information to model a vascular site of interest and provide results from modeling the vascular site of interest. The system also includes interfaces for transmitting information from the input module and the database to the FSI solver and for receiving the results from the FSI solver, and an ensemble of analysis modules which is coupled to the interface for receiving results. The ensemble of analysis modules compares various treatment options, allows before-and-after comparisons of aspects of the vascular site of interest and provides quantitative assessments of parameters of interest describing the vascular site of interest.Type: ApplicationFiled: November 24, 2008Publication date: May 27, 2010Applicant: GENERAL ELECTRIC COMPANYInventors: Andras Lasso, Ferenc Nasztanovics
