将层到体自动配准算法与人工配准进行对照,评估该技术的临床实用性。回顾从一个下腹部诊断性CT检查中得到重组图像并由41个人进行人工配准,用算法对结果进行优化。进一步进行无人工初始化的单层到所有CT图像全自动配准。发现旋转和平移人工配准误差为(2.7±2.8)°和(4.0±2.5)mm。自动配 The layer to body automatic registration algorithm is compared with manual registration to evaluate the clinical utility of the technique. Recall that a reconstructed image was obtained from a lower abdominal diagnostic CT scan and manually registered by 41 individuals. The algorithm was used to optimize the results. Further unmanned initialization of all layers to all CT images Fully automatic registration. The manual registration errors for rotation and translation were found to be (2.7 ± 2.8) ° and (4.0 ± 2.5) mm. Automatic with
