Intraoperative Video Display

Once the images have been registered with respect to the patient, they must be displayed in a meaningful manner. A high-resolution monitor with 512 X 512 pixel windows displays images in a variety of orientations and configurations. Color graphic overlays that represent the localizer position and trajectory are usually displayed relative to the on-screen images. The local-izer position is usually updated on the screen at 20 frames per second. Realtime displays have become more common with increases in image processing speed and power and decreases in cost.
