Patent number: 8482606Abstract: A system and method of providing composite real-time dynamic imagery of a medical procedure site from multiple modalities which continuously and immediately depicts the current state and condition of the medical procedure site synchronously with respect to each modality and without undue latency is disclosed. The composite real-time dynamic imagery may be provided by spatially registering multiple real-time dynamic video streams from the multiple modalities to each other. Spatially registering the multiple real-time dynamic video streams to each other may provide a continuous and immediate depiction of the medical procedure site with an unobstructed and detailed view of a region of interest at the medical procedure site at multiple depths.Type: GrantFiled: April 14, 2010Date of Patent: July 9, 2013Assignee: Inneroptic Technology, Inc.Inventors: Sharif Razzaque, Kurtis Keller, Andrei State, Caroline Green, Jeremy Ackerman

Patent number: 8340379Abstract: Presented herein are methods, systems, and computer-readable medium for presenting imaging data related to an anatomical site. These include obtaining a first set of imaging data related to the anatomical site and tracking units at the anatomical site and, thereafter, optionally, obtaining a second set of imaging data related to the anatomical site. A deformed version of the first set of imaging data is then determined based on the relative arrangements of one or more of the tracking units at the time when the first set of imaging data is obtained and when the second set of imaging data is obtained. Then the relative emplacements of the second set of imaging data set and of the deformed version of the first set of imaging data set are determined and used, along with the second set of imaging data set and the deformed version of the first set of imaging data, as a basis for displaying image guidance data.Type: GrantFiled: March 6, 2009Date of Patent: December 25, 2012Assignee: Inneroptic Technology, Inc.Inventors: Sharif Razzaque, Andrei State

Publication number: 20110130641Abstract: Various embodiments herein provide for imager focusing based on intraoperative data. Ideally, an imaging plane of an ultrasound transducer would be truly planar. That is not the case, though. Instead, ultrasound transducers image a volume that is closer to a rectangular volume, but that has focal depths or areas in the imaged volume that are “thinner” and provide a better resolution. In general, embodiments herein may include determining the pose of an imager, such as an ultrasound transducer, and the pose of a location of interest. Based on those poses, a focal adjustment may be determined in order to, for example, better focus the imager on the object of interest. Then data is generated and the focus of the imager is adjusted. Additionally, imaging data and/or the object of interest may be displayed. In other embodiments, estimated projections of medical devices are displayed to allow for better intraoperative planning.Type: ApplicationFiled: November 18, 2010Publication date: June 2, 2011Applicant: InnerOptic Technology, Inc.Inventors: Sharif Razzaque, Andrei State, Kurtis Keller

Publication number: 20110057930Abstract: A system and method for providing high-speed, high-resolution three-dimensional imagery for endoscopy, particularly of a tissue surface at a medical procedure site is disclosed. High-resolution imagery provides greater detail of the tissue surface, but requires high-speed depth-frame imaging to provide timely updated depth information. A pattern of light, such as a point of light for example, may be projected onto the tissue surface and a reflected image analyzed to determine depth information. The point of light can be projected and analyzed quickly to produce faster depth-frame image rates. Three-dimensional structured-light depth resolution information may be generated and combined with either a two-dimensional image or a two-dimensional stereo image to provide three-dimensional imagery of the tissue surface. Switching between three-dimensional images and one of the two-dimensional image and a two-dimensional stereo image may also be provided.Type: ApplicationFiled: November 10, 2010Publication date: March 10, 2011Applicant: INNEROPTIC TECHNOLOGY INC.Inventors: Kurtis P.

Publication number: 20100045783Abstract: Methods and systems for dynamic virtual convergence (218) and a video see through head mountable display (200) that uses dynamic virtual convergence are disclosed. A dynamic virtual convergence algorithm (218) includes sampling an image with two cameras. The cameras each have a field of view that is larger than a field of view of displays used to display images sampled by the cameras (210). A heuristic is used to estimate the gaze distance of the viewer. The display frustums are transformed so that they converge at the estimated gaze distance. The images sampled by the cameras (210) are then reprojected into the transformed display frustums. The reprojected images are displayed to the user to simulate viewing of close range objects.Type: ApplicationFiled: October 30, 2009Publication date: February 25, 2010Inventors: Andrei State, Kurtis P.

Publication number: 20090312629Abstract: Presented herein are methods, systems, devices, and computer-readable media for correction of relative tracking error based on a fiducial. One embodiment is a method for the correction of obtained emplacement data of two surgical instruments by the detection of a detectable fiducial coupled to first surgical instrument by a second surgical instrument or something thereto coupled. The corrected relative emplacements of both surgical instruments is then determined based on the emplacement of the fiducial. This corrected emplacement is then used to produce an image for display. Systems and devices for carrying out the presented methods are also described.Type: ApplicationFiled: June 11, 2009Publication date: December 17, 2009Applicant: INNEROPTIC TECHNOLOGY INC.Inventors: Sharif Razzaque, Andrei State, Caroline Green, Kurtis Keller
