The N-localizer and the Sturm-Pastyr localizer are two technologies that facilitate image-guided stereotactic surgery. Both localizers enable the geometric transformation of tomographic image data from the two-dimensional coordinate system of a medical image into the three-dimensional coordinate system of the stereotactic frame. Monte Carlo simulations reveal that the Sturm-Pastyr localizer is less accurate than the N-localizer in the presence of image noise.
N定位器和Sturm-Pastyr定位器是两种有助于图像引导立体定向手术的技术。这两种定位器都能将断层图像数据从医学图像的二维坐标系转换成立体定向框架的三维坐标系。蒙特卡洛模拟显示,在存在图像噪声的情况下,Sturm-Pastyr定位器的准确性不如N定位器。
