Abstract
An image guided surgical system includes a marker attachable to and removable from an elongated surgical tool having a shaft, and at least one camera, and an image processing system in communication with the camera configured to obtain an image of the surgical tool. The image processing system is configured to operate in a calibration mode to generate a template and display the template on a display device and to receive a user input, after the image of the surgical tool is aligned to the template, to adjust a length of the template to substantially match a length of the surgical tool. A storage device in communication with the image processing system is included to store calibration information that associates a position of the marker with a position of the tip of the shaft of the surgical tool based on the adjusted length of the template.
