METHOD AND SYSTEM FOR SURGICAL INSTRUMENT GUIDANCE AND TRACKING WITH POSITION AND ORIENTATION CORRECTION

摘要

The present teaching relates to surgical procedure assistance. In one example, a first image of an organ having a lesion is obtained prior to a surgical procedure. Information related to a pose of a surgical instrument at a first location with respect to the lesion is received from a sensor coupled with the surgical instrument. A visual environment having the lesion and the surgical instrument rendered therein is generated based on the first image and the information received from the sensor. A second image of the organ is obtained when the surgical instrument is moved to a second location with respect to the lesion during the surgical procedure. The second image captures the lesion and the surgical instrument. The pose of the surgical instrument and the lesion rendered in the visual environment are adjusted based, at least in part, on the second image.
