Apparatus and methods are disclosed for the calibration of a tracked imaging probe for use in image-guided surgical systems. The invention uses actual image data collected from an easily constructed calibration jig to provide data for the calibration algorithm. The calibration algorithm analytically develops a geometric relationship between the probe and the image so objects appearing in the collected image can be accurately described with reference to the probe. The invention can be used with either two or three dimensional image data-sets. The invention also has the ability to automatically determine the image scale factor when two dimensional data-sets are used.

A surgical instrument navigation system is disclosed that allows a surgeon to invert the three-dimensional perspective of the instrument to match their perspective of the actual instrument. A data processor is operable to generate a three-dimensional representation of a surgical instrument as it would visually appear from either of at least two different perspectives and to overlay the representation of the surgical instrument onto an image data of the patient. The image data and the representations can be displayed on a display.

A surgical instrument navigation system is provided that allows a surgeon to invert the three-dimensional perspective of the instrument to match their perspective of the actual instrument. The surgical instrument navigation system includes: a surgical instrument; an imaging device that is operable to capture image data representative of a patient; a tracking subsystem that is operable to capture in real-time position data indicative of the position of the surgical instrument; and a data processor adapted to receive the image data from the imaging device and the position data from the tracking subsystem. The data processor is operable to generate a three-dimensional representation of the surgical instrument as it would visually appear from either of at least two different perspectives and to overlay the representation of the surgical instrument onto the image data of the patient. The navigation system further includes a display that is operable to display the representation of the surgical instrument superimposed onto the image data of the patient.

A method and apparatus are disclosed that provides a system to perform a procedure on a patient or on a patient's anatomy. The apparatus can include a guide member that includes at least three degrees of freedom of movement of a guide or alignment portion. The apparatus can be used to guide or form reference points for a guide to resect a portion of an anatomy.

A surgical apparatus is configured to support at least one bone cut for installation of a prosthetic component. The installed prosthetic component will have reduced alignment error. The surgical apparatus is configured to distract a first compartment to a first predetermined load value while allowing a moving support structure to pivot freely. A distraction lock mechanism is then engaged to prevent movement of a distraction mechanism that raises or lowers the moving support structure relative to a fixed support structure. The moving support structure has M-L tilt angle that is measured. A M-L tilt mechanism is engaged to forcibly equalize the first and second compartments. Engaging the M-L tilt mechanism prevents the moving support structure from freely pivoting. The at least one bone cut relates to the first and second compartments equalized and the M-L tilt angle.
