Abstract: A method for marking three-dimensional (3D) locations from images obtained from an ultrasound imaging system including a transducer, comprising the steps of: tracking the pose of the transducer with respect to an external 3D coordinate system; obtaining a two-dimensional (2D) ultrasound image from the transducer; marking a desired target with a marker on the 2D ultrasound image; and calculating the 3D position of the marker utilizing data from the step of tracking.

Abstract: Disclosed is a room planning and design system, comprising a virtual room space comprising a virtual representation of a physical room space, an object library of virtual objects, said virtual objects comprising virtual representations of equipment, machines and objects that may be placed in a room, a user interface comprising a first user interface component for selecting said virtual objects from said virtual library and positioning them in said virtual room space, a second user interface component for manipulating the positions and orientations of said virtual objects within said virtual room space, a workspace comprising a physical model of said physical room space, physical marker objects substantially scaled to said workspace for manual placement and orientation of said markers objects in said workspace, one or more detectors for detecting information regarding the positioning of said marker objects in said workspace and transmitting said information to a visualization module, and said visualization mod

Abstract: A method and system for computer assisted site navigation comprises the steps of capturing an image of a scene for providing real-time image data; calibrating the camera and localizing the image by utilizing the image data and retrieved marker registration and floor-map data for providing position and orientation data; transmitting the data to a web server; utilizing the image data and information on the scene retrieved from a database for deriving an augmented view; and displaying the augmented view.

Abstract: A method for determining the best entry point for a percutaneous procedure, such as with a biopsy needle, comprises selecting first and second arbitrary entry points on a patient; determining the three dimensional (3-D) orientation of the needle at the first arbitrary entry point for pointing the needle at the primary target; determining the 3-D orientation of the needle at the first arbitrary entry point for pointing the needle at the secondary target; determining the 3-D dimensional orientation of the needle at the second arbitrary entry point for pointing the needle at the primary target; determining the 3-D orientation of the needle at the second arbitrary entry point for pointing the needle at the secondary target; determining a 3-D line representing the intersection of a first plane containing the first arbitrary entry point, the primary target point, and the secondary target point, and a second plane containing the second arbitrary entry point, the primary target, and the secondary target point, whereb
