A method of contouring spinal rods, and systems therefor. The surgeon uses image guided surgery instruments to identify the locations of the screw heads through which the rod will pass. These locations allow a computer to form a best fit line that corresponds to the shape of a rod that can pass through the screw heads. This best fit line is then displayed on a projection table from both its coronal and sagittal views. The surgeon then shapes the rod using these 2-D images as a template.

A dithering pattern that is generated based on a spatial operation is used for a Bit-Depth Extension (BDE) technique for preventing contouring artifacts in an image displayed by a display having a bit-depth that-is less than the bit-depth of the image. The dithering pattern can be based on achromatic visual model or a spatio-chromatic visual model. The dither pattern is formed by shaping a pseudo-random noise signal by an equivalent noise visual model that is based on an array of pixels. Alternatively, the array of pixels is based on an image, or a determinate array of pixels.

Pedicle screws are designed to provide polyaxial coupling to pedicles of a vertebra. Intermediate pieces are attached to the pedicles screws and receive extender shafts. Extenders are inserted in the intermediate piece. The extenders project the anatomic points located in the cage outside the patient's body to facilitate proper contouring of a rod. An alignment linkage is used to ensure that the extenders are parallel to each other. The alignment linkage includes a linkage frame, an articulating linkage and a locking member. The articulating linkage has all rotational degrees of freedom and thereby adapts to any varying trajectories of the extenders and distance between the extenders. The alignment linkage includes a locking member with a pop-up indicator. The pop-up indicator notifies the users when the locking member is tightened with two of the extenders in non-parallel configuration.
