Abstract: A system and method for displaying surgical instruments accurately, in both time and space, within both slice and volumetric medical images of organs that may deform in a predictable manner over time due to an ongoing body activity. The system and method comprising using a gating signal associated with an ongoing body activity to determine which image in a sequence of acquired images best represents the state of the imaged anatomy at a given point in time and accurately displaying navigated surgical instruments within that image at that point in time.

Abstract: Systems and methods for tracking a surgical instrument and for conveying tracking information via a network provide a primary tracking image generally within an operating room, and also a variety of types of secondary tracking images, either outside of the operating room or within the operating room.

Abstract: A user interface is provided for manipulation of image data. In some embodiments, the interface includes a display region spanning only a locus of interdependent variable values that is exclusive of invalid pairs of parameter values.
