摘要： A system for navigating and guiding a surgical instrument during a surgical procedure. A transmitter is positioned near a patient's anatomy. A receiver is attached to the surgical instrument. The position of the surgical instrument is tracked using the transmitter and receiver. A processing unit determines the location of the surgical instrument relative to the patient's anatomy and produces images with a pictorial representation of the surgical instrument and the patient's anatomy. The images are displayed on a display. A surgeon can view the images on the display and guide the surgical instrument into position inside the patient. The surgical instrument can be guided inside a patient without continuously producing real time x-ray exposures. Positions of the surgical instrument can be saved and displayed on the display along with the pictorial representation of the surgical instrument in its current position.

摘要： Certain embodiments of the present invention provide a system and method for calibrating an instrument for an image-guided operation. The method includes placing a plurality of fiducials on an instrument, obtaining a plurality of measurements for the instrument using the plurality of fiducials, determining a representation of the instrument in a reference coordinate system using the plurality of measurements for use in tracking the instrument, and performing an image-guided operation using an image data set and representation of the instrument. The representation may be a closed form registration for the instrument. The measurements for the instrument may be obtained using a plurality of fiducials and a sensor. The fiducials may be indentations and/or grooves in the instrument. In an embodiment, the representation of the instrument is dynamically updated during an image-guided operation. In an embodiment, the representation of the instrument is compared to a computer-generated model of the instrument.

摘要： Assistive motion data processing and/or button data processing is performed in an adapter on user inputted variable data produced by a pointing device prior to communication to a computer. This processing may include one or more of processing to filter coordinate deviations from a desired path caused by unintended movements of the pointing device; removal of unintentional rapid button transitions of the pointing device; look-back processing to correct for unintentional pointer coordinate motion induced by operation of buttons on the pointing device; and detection of button double-clicks using relaxed requirements on motion and timing. The adapter's processing is transparent to the computer. Provision for user input of selected parameters is provided, as well as switching to allow for user deactivation of the adapter for conventional use of the pointing device.

摘要： One or more implementations are described herein for improved instrument tracking. In a surgical navigation system, one implementation stores a plan for an image guided procedure, before conducting the procedure. This plan includes a path to be traversed by a medical instrument during the procedure. An image of the patient's anatomy displayed with a superimposed a pictorial representation of the path on the image. A transpoder coupled to the medical instrument and emits a signal while inside the patient's body. A position and/or orientation of the transponder (and the instrument) is determined based, at least in part, upon the received transponder signal.

摘要： A system and method for embedding tracking technology in a medical table is disclosed. A plurality of table sensors is attached to a medical table to form an array. An instrument sensor is attached to an instrument. At least one of the table sensors and the instrument sensor generates at least one magnetic dipole field. The instrument sensor is moved relative to the array while at least one of the table sensors and the instrument sensor measures at least one vector component of the field. The measured vector component(s) are communicated to tracker electronics that determine at least one of a position and orientation of the instrument sensor relative to the array.

摘要： There is provided a hand held cursor controller system for use particularly with interactive television and computer presentation graphics. The system uses a hand held device with infrared light emitting diodes which transmits to a detector attached to a processor. The information from the processor is transmitted to a television or video cassette recorder. The system allows for the positioning of a cursor on a television screen with the only input of the user being the aiming of the controller. It includes push-button activation and provides for the transmission of the usual controller codes.

摘要： A computer system and method determines the force and/or torque applied during the image acquisition stage of a biometric characteristic. Images with very high or very low pressure or high shear torque are rejected and user/operator is notified to re-acquire the image. Alternatively, the application of force and torque by the subject is restricted mechanically so that the images are acquired while the force and/or torque are within acceptable ranges.
