Objective: 3-D ultrasound technology can help to solve the orientation difficulties experienced previously with two-dimensional ultrasound. So called two-platform solutions offering this novel technology tend to prolong operative time due to the calibration procedure, or they display the two imaging modalities on separate monitor screens. A novel operative image guided one-platform system overcomes these disadvantages and combines 3D ultrasound images with the usual navigation images.

Methods: The new ultrasound system (IGsonic) is integrated into a neuronavigation system. We have used intraoperative 3-D ultrasound data acquisition for 31 patients with intracranial lesions. 256 slices were collected per data set and ultrasound data was reconstruced based on spatial resolution. The 3D-ultrasound data was fused to the preoperative data via registration and the reference coordinate system, no coregistration was necessary.

Results: The system worked properly during all procedures. It displays a reconstruction view of 3D-ultrasound (axial, sagittal, coronal) and live ultrasound in combination with the preoperatively-acquired neuronavigational data (CT or MRI) or the 3D-ultrasound. As an option, the ultrasound image can be displayed in a semitransparent color overlay mode (green overlay) technology. It provides intraoperative image updating for repeated data sets. 3D-ultrasound provides online information on the progress of surgery and displays the pre- or intraoperatively acquired information, such as labeled points, trajectories or objects.

Conclusions: Intraoperative navigated 3-D ultrasound represents a significant improvement for orientation, because it provides an instant and updated three dimensional orientation as well as an accurate map of the patient's true anatomy at various stages of the operation. The green overlay of real-time ultrasound images can be compared with the corresponding 3D-ultrasound reconstruction. Furthermore, composition of 3D reconstructed ultrasound images with the preoperative navigation data set is displayed on a single screen.
