The NeuroMate™ robot System ISS (Integrated Surgical Systems, Davis, CA) is an image-guided, robotic-assisted system for brain surgery, which is a commercially available system used today for stereotactic procedures in neurosurgery. In this paper we describe an accuracy studies for the NeuroMate system. We present a quantitative comparison of the application accuracy of the NeuroMate to standard frame based and frameless stereotactic techniques. The study discusses a five-way application accuracy comparison study. The variables of our comparison and their mean errors are: 1) In the robot in a frame-based configuration, the RMS was 0.86 ± 0.32mm; 2) In the robot in the frame-less configuration, the RMS was 1.95 ± 0.44mm; 3) In a Standard Stereotactic (ZD) frame-based approach, the RMS was 1.17 ± 0.25mm; 4) In an infrared tracking system (IR) using the frame for the fiducial registration, the RMS was 1.47 ± 0.45mm; 5) In an infrared tracking system using screw markers as the registration, the RMS was 0.68 ± 0.26mm. The study was done with 2mm sections of CT scans. These results showed that the application accuracy of the frame-based NeuroMate robot is comparable to standard localizing systems whether they are frame-base or infrared tracked.
