Abstract: A facility for processing data update messages is described. The facility establishes a plurality of units of execution each for executing data update message processing code. The facility receives data update messages from a plurality of sending devices, and assigns each received data update message to a unit of execution without regard for which sending device it was received from. In each unit of execution, the facility executes the code to process the received data update messages to which it is assigned.

Abstract: A method for filtering garbage data, including: a garbage data path value and a garbage data filtering rule are preset, based on an instruction received from the outside; a garbage data scanning point is determined, by parsing the garbage data path value; each file in the garbage data scanning point is scanned, so as to determine whether the each file is the garbage data, based on the garbage data filtering rule.

Abstract: The present discussion relates to automated image data processing and visualization. One example can facilitate generating a graphical user-interface (GUI) from image data that includes multiple semantically-labeled user-selectable anatomical structures. This example can receive a user selection of an individual semantically-labeled user-selectable anatomical structure. The example can locate a sub-set of the image data associated with the individual semantically-labeled user-selectable anatomical structure and can cause presentation of the sub-set of the image data on a subsequent GUI.

Abstract: As a general overview, the system 10 is used to assist the surgeon in performing an operation by acquiring and displaying an image of the patent. Subsequent movement of the patient and instruments is tracked and displayed on the image. Images of a selection of implants are stored by the system and may be called to be superimposed on the image. The surgical procedures may be planned using the images of the patient and instruments and implants and stored as a series of sequential tasks referred to defined datums, such as inclination or position. Gestures of the surgeon may be used in the planning stage to call the image of the instruments and in the procedure to increment the planned tasks.

Abstract: A method and apparatus are disclosed for defining a three-dimensional coordinate system in relation to an anatomical structure (64) for use with computer-assisted surgical systems. At least three landmarks (66, 68, 70) associated with the anatomical structure (64) are identified. Landmarks are identified using a digitization device (96) and their location refined using at least one single calibrated X-ray image. Using the landmarks (66, 68, 70), first and second planes are defined, the second plane being orthogonal to the first plane. These planes define a coordinate system, which can be used to ascertain the position trajectory of any object (80) with respect to the anatomical structure. Exposure to imaging radiation and additional surgical procedure is minimized.
