Abstract: Described herein are systems, methods, and techniques for spatially-aware displays for computer-assisted interventions. A Fixed View Frustum technique renders computer images on the display using a perspective based on a virtual camera having a field-of-view facing the display and automatically updates the virtual position of the virtual camera in response to adjusting the pose of the display. A Dynamic Mirror View Frustum technique renders computer images on the display using a perspective based on a field-of-view of a virtual camera that has a virtual position behind the display device. The virtual position of the virtual camera is dynamically updated in response to movement of a user's viewpoint located in front of the display device. Slice visualization techniques are also described herein for use with the Fixed View Frustum and Dynamic Mirror View Frustum techniques.

Abstract: In a method for filling a predefined cylindrical container, a closed filling valve is moved with its filling tip through the container opening into the container. A gas contained in the container is displaced or compressed in the container. The container opening is sealed about the filling valve; the point in time of sealing determines a pressure in the container. The container is filled by opening the filling valve to allow fluid flow. The end face of the filling valve is below a fluid level in a radial gap volume between container wall and filling valve. Upward movement of the filling valve is adjusted according to predefined control parameters; filling occurs below fluid level in that the fluid level is above the end face of the filling valve. The filing valve is closed upon reaching the predefined filling volume. The closed filling valve is removed from the container.

Abstract: In a method for filling a bottle, a balloon body extends through an axial through bore of a cap and is connected seal-tightly with an upper circumferential rim to the cap above a radial opening of the cap. An elongate support associated with the balloon body is connected to the cap. Balloon and elongate support are inserted into the bottle. The cap is positioned at a spacing above the bottle neck to form a ring-shaped intermediate gap. Air contained in the bottle interior is forced out through the intermediate gap by inflating the balloon body with an expansion medium. Subsequently, the cap is fluid-tightly fitted on the bottle neck. The expansion medium is allowed to escape from the balloon body and liquid is supplied through radial and axial openings of the cap into the space between outer surface of the balloon body and inner bottle wall.

Abstract: A liquid filling apparatus has a vertical tube with bottom opening opened and closed by a valve. The tube is insertable into a container from above and supplies liquid to the container. A flexible separating disk extends radially from the bottom end of the tube. The tube with flexible separating disk is movable toward the container bottom and air in the container escapes between peripheral rim of the separating disk and container wall as the tube moves down until the flexible separating disk rests on the container bottom. The tube with flexible separating disk then is moved upwardly so that, between flexible separating disk and container bottom, an enlarging space is formed with upward movement. Liquid is supplied into this space through the open tube opening as upward movement continues. When a targeted liquid level is reached, the valve closes and the tube is pulled from the container.

Abstract: The present invention relates to a method for filling a fluid into a container without using measuring means and to a filling apparatus therefor which comprises an attachment having a predetermined volume VA, said attachment comprising a valve attachment which has a gas valve and a liquid valve with a valve seat in a housing.

Abstract: A technique for determining a transformation between a navigation reference coordinate system (302) for navigation of a surgical device (150) relative to patient image data and an image coordinate system (304) in which the patient image data define a shape of a patient surface is provided. A computer-implemented method implementation of that technique comprises receiving multiple data sets that have been taken from different perspectives of the patient surface. Feature coordinates of multiple features (170) identifiable in the picture data sets are determined from the picture data sets and in the navigation reference coordinate system (302). From the feature coordinates, a shape model of the patient surface in the navigation reference coordinate system (302) is determined.

Abstract: A system is disclosed for determining a position and a change in the position of an anatomical structure. The system utilizes a surgical navigation system and a substrate that is capable of being removably mounted to an outer surface of a patient's body. The substrate includes a sensor that is tracked by the surgical navigation system and a positional device that determines the position of an anatomical structure relative to the sensor. The concatenation of the position of the sensor and the relative position of the anatomical structure allows a global position of the anatomical structure to be determined by a computer system and displayed to the user.

Abstract: A system and method for planning volumetric treatment by percutaneous needle procedures obtains a volumetric image data set of a subject including an identifiable region requiring treatment. An effective treatment volume is defined relative to the needle position for at least one needle carrying a treatment applicator. One or more proposed inserted needle position is defined such that a effective treatment volume corresponding to the one or more proposed inserted needle position provides coverage of the region requiring treatment. The effective treatment volume for one or more needles can then be visualized in the context of slices of 3D image data. One or more entry point and corresponding virtual target are then defined relative to a frame of reference of the volumetric image data set for use in navigation of the at least one needle to the corresponding proposed inserted needle position.
