Abstract
Certain embodiments of the present invention provide for a system and method for assessing the accuracy of a surgical navigation system. The method may include acquiring an X-ray image that captures a surgical instrument. The method may also include segmenting the surgical instrument in the X-ray image. In an embodiment, the segmenting may be performed using edge detection or pattern recognition. The distance between the predicted location of the surgical instrument tip and the actual location of the surgical instrument tip may be computed. The distance between the predicted location of the surgical instrument tip and the actual location of the surgical instrument tip may be compared with a threshold value. If the distance between the predicted location of the surgical instrument tip and the actual location of the surgical instrument tip is greater than the threshold value, the user may be alerted.
