A computer software program (Seapit) was developed for precise determination of intracranial targets identified by stereotactic computed tomography (CT). This program was added to the software of a GE 8800 CT scanner to perform the following operations: millimetre precise calculation and display of the rectilinear coordinates of a target identified on axial CT images; preplotting of phantom target trajectories on the CT images or electronic radiographs; calculation of probe angles required to achieve various trajectories; display of a coordinate scale on each CT image to allow direct target determination without mathematical calculations; calculation of the intercommissural plane for functional neurosurgery. In a series of 100 patients undergoing stereotactic surgery, the Seapit program proved to be a superior and accurate method of target coordinate calculation. Preview display on the CT images of 'phantom' probes significantly enhanced the safety of stereotactic intervention.
开发了一种计算机软件程序（Seapit），用于精确确定立体定向计算机断层扫描（CT）所识别的颅内靶点。该程序被添加到GE 8800 CT扫描仪的软件中，以执行以下操作：对轴向CT图像上识别出的靶点进行毫米级精确计算并显示其直角坐标；在CT图像或电子放射照片上预先绘制虚拟靶点轨迹；计算实现各种轨迹所需的探头角度；在每张CT图像上显示坐标刻度，以便无需数学计算即可直接确定靶点；计算功能神经外科手术的连合间平面。在一系列100例接受立体定向手术的患者中，Seapit程序被证明是一种更优越且准确的靶点坐标计算方法。在CT图像上对“虚拟”探头进行预览显示显著提高了立体定向干预的安全性。
