Three-Dimensional Image-Guided Navigation with Overlaid Three-Dimensional Image (Volumegraph) and Volumetric Ultrasonogram (V-US)
Augmented reality is necessary for minimally invasive surgery. Recent medical imaging technology developments, such as X-ray, computed tomography (CT), and magnetic resonance imaging (MRI), have changed the methods and the dimensions of observation of the human body. Such image data are required for preoperative investigation to recognize the structure of organs and tumors three-dimensionally. Three-dimensional images seen in the air by means of a beamed light have been reported previously. The images are superimposed on the patient’s head and body via a semitransparent mirror. We have applied these techniques to the navigation system for neurosurgical operations. The three-dimensional data obtained from CT and MRI before the operation were processed by a computer. This reconstructed three-dimensional image was superimposed and registered at the patient’s head according to fiduciary markers (registration). The application of augmented reality in the surgical field makes it possible to do a neurosurgical intervention more easily. The surgeon can operate by this three-dimensional image-guided navigation system easily and accurately. In the development of volumetric ultrasonogram (VUS) navigation, the distortion of the brain during surgery is the key problem for truly accurate and effective guidance.
