Abstract: This patent includes a method to generate a six dimensional audio dataset. When listening to the six dimensional audio dataset with an advanced headset disclosed in this patent, a user will enable a user to have precision sound localization and maximize the listening experience. For example, when the audio file is registered to a living room, a user would be able to sit in the “middle of the band” and if desired, reposition the instruments to different locations within the living room to change the audio experience.

Abstract: An interactive 3D cursor facilitates selection and manipulation of a three-dimensional volume from a three-dimensional image. The selected volume image may be transparency-adjusted and filtered to remove selected tissues from view. Qualitative and quantitative analysis of tissues in a selected volume may be performed. Location indicators, annotations, and registration markers may be overlaid on selected volume images.

Abstract: This patent includes a method for displaying a 2D image on a non-planar display with a top portion of said non-planar display curving inwards towards a user's viewing position, a bottom portion of said non-planar display curves inwards towards said user's viewing position, a left portion of said non-planar display curves inward towards said user's viewing position and a right portion of said non-planar display curves inward towards said user's viewing position. This type of display can be used as a virtual display for extended reality head display units including virtual reality, augmented reality or mixed reality displays. For a virtual display, advanced features can be performed including stereoscopic viewing the screen with a convergence point shifting technique, zooming and rotating to maximize usability. The virtual display can be modified in its horizontal curvature or vertical curvature per user preference.

Abstract: A method and apparatus comprising generating a dynamic personalized webpage is disclosed. At least two webpages are loaded in a fashion that is hidden from the user. Content from the at least two webpages is extracted based on classification “of interest” by an artificial intelligence algorithm. A dynamic personalized webpage comprising extracted content is then generated and displayed to the user. In the preferred embodiment, the user's dynamic personalized webpage will be filled with advertisements tailored to the user and the user would receive at least some revenue from advertisements.

Abstract: A physician performing a physical examination can miss subtle abnormalities, such as alterations of respiratory rate or dangerous skin lesion. A surgeon performing surgery can miss small areas of bleeding or tumor implants. This invention comprises head display unit comprising sensors including low light level TV (L3TV) cameras that gather data and in real time analyzes the data for potential hazards and alerts the user of a potential hazardous scenario.

Abstract: Virtual tools are used to manipulate aspects of a three-dimensional medical image volume. The virtual tools are geo-registered with the image volume. Presentation of the image volume is manipulated by an image processor in response to use of the virtual tools. The virtual tools may be used to facilitate analysis of the image volume. The virtual tools may include: a virtual focal point pen; a virtual 3D cursor; a virtual transport viewer; a virtual pedestal; a virtual knife; a virtual catheter; a virtual road sign; a virtual ablation tool; a virtual table; a virtual contrast tool; and virtual icons.

Abstract: This patent provides a novel set of stereoscopic imaging techniques. Such techniques allow extremely large field of view datasets capable of stereoscopic display, such as greater than 270° horizontal field of view and 180° vertical field of view. Thus it is possible to record data in a way that is larger than a user could visualize. A user can thus select which subset of the dataset he/she wants to view. Then, allow the user to view naturally via head tracking and eye tracking to allow one to see and inspect a scene as if one were naturally there viewing it in real time.

Abstract: This patent includes techniques for improved rates of display of images within an image set. This is particularly useful to scrolling through medical images. For example, the top of the head on an axial head CT image is a smaller size on the screen as compared to the middle of the head. This patent provides a method for image analysis and medical history analysis to optimize scrolling rates.

Abstract: A method and apparatus is disclosed, which improves the analysis of an object within a scanned bag. Specifically, the techniques disclosed herein overcome the problem of measurement errors due to imaging artifacts, which can occur during imaging examinations like CT scans. This process also discloses a method of using an improved accuracy of data units of an object lead to more accurate classification of the material that makes up the object.

Abstract: Pointers are added to a 3D volumetric dataset to help the user visualize the direction of blood flow. A 3D volume containing at least one blood vessel is created. Next, the direction of the blood flow is determined. Next, at least pointer is placed into the 3D volume in an aligned fashion with the direction of blood flow such that the 3D volume is modified. Next, the modified 3D volume is displayed on a head display unit, such as an augmented reality or virtual reality display. Next, at least one pointer is advanced to a new position for additional modification of the 3D imaging volume.

Abstract: A method and apparatus for improvement of spatial resolution in molecular and radiological imaging is presented. System equipment includes bed with either flat or cylindrical detectors large detector arrays with collimator(s), lens(s), mirror(s) and/or shutter(s). This system utilizes magnification principles with large detector arrays. There is error reduction by reduction of non-collinearity error as seen in current PET scans by determination of the trajectory of the photons and accurate localization of the annihilation event of a positron. Additional error reduction of random coincidence and scatter coincidence is seen. Overall, this method and apparatus affords improved spatial resolution and higher efficiencies, which would allow for lower cost and dose reduction to the patient.

Abstract: Virtual objects can be affixed to geo-registered tools (e.g., platform, knife, etc.) that interact with items (e.g., anatomic structures) within 3D volumes. For example, a 27-foot virtual wand can be affixed to a 1-foot long geo-registered wand and the resulting multi-part wand can be moved another two feet within a 3D volume in response to movement of the geo-registered wand to reach an object 30 feet away in the 3D volume. Various other interaction techniques are disclosed. The techniques may be used in a variety of applications possibly including, but not limited to, medicine, gaming, education, carpentry, manufacturing, or other industries.
