Clinical use of the invisible target calculation software

Objective To analyze the results of the actual target coordinates and the calculation coordinates with the calculation software STZ. Methods 8 groups coordinates from 7 patients with good operation results on whom pallidotomy / thalamotomy had been performed had been calculated by our calculation software STZ, and compared with the actual coordinates of operation. Difference between the actual and calculation coordinates was measured by randomized paired design t test. Results statistical significance was considered at P 0.9,there are no difference between the two groups. Conclusion Determination of invisible target by using our STZ calculation software has proved to be very accurate and rapid and easy to use. And there is no need for CT/MRI scans that AC and PC on the same slice.
