    摘要: A method and apparatus for electromagnetic navigation of a surgical probe near a metal object. The electromagnetic navigation system includes a transmitter coil array and a shield. The transmitter coil array has a plurality of transmitter coils and is operable to generate the electromagnetic field to navigate the probe. The shield is positioned adjacent the metal object and is operable to shield the metal object from the electromagnetic field generated by the transmitter coil array, such that the shield substantially reduces distortion of the electromagnetic field by the metal object.

    摘要: A surgical instrument navigation system is provided that visually simulates a virtual volumetric scene of a body cavity of a patient from a point of view of a surgical instrument residing in the cavity of the patient. The surgical instrument navigation system includes: a surgical instrument; an imaging device which is operable to capture scan data representative of an internal region of interest within a given patient; a tracking subsystem that employs electromagnetic sensing to capture in real-time position data indicative of the position of the surgical instrument; a data processor which is operable to render a volumetric perspective image of the internal region of interest from a point of view of the surgical instrument; and a display which is operable to display the volumetric perspective image of the patient.

    摘要: A surgical instrument navigation system comprises an ultrasound machine and a computer coupled to the ultrasound machine. A memory is coupled to the computer and includes computer instructions that when executed by the computer cause the computer to generate an icon representing the surgical instrument with a tip and the surgical instrument's trajectory and to overlay the icon on a real-time ultrasound image having an image plane, such that when the surgical instrument crosses the ultrasound image plane the format of the surgical instrument's trajectory is changed to represent the surgical instrument's crossing of the ultrasound image's plane. The system also comprises a localizer coupled to the ultrasound machine, and a display coupled to the computer for displaying the generated icon superimposed on the real-time image.

    摘要: A system for utilizing and registering at least two surgical navigation systems during stereotactic surgery. The system comprises a first surgical navigation system defining a first patient space, a second surgical navigation system defining a second patient space, and a translation device to register the coordinates of the first patient space to the coordinates of the second patient space. The translation device comprises a rigid body, at least one component for a first navigation system placed in or on the rigid body, and at least one component for a second navigation system placed in or on the rigid body, in known relation to the at least one component for the first navigation system. The translation device is positioned in a working volume of each of the at least two navigation systems.
