医学影像可视化的一个重要分支——三维重建技术在临床学领域一直发挥着重要的作用，同时也是计算机领域一直 关注的热点问题。从三维图像入手，医生可以更加精准地判断患者病灶的形态、状况和位置等，从而提高诊断的准确性。 本文针对CT图像的预处理和分割结果做进一步研究，在腹腔二维切片感兴趣器官分割的基础上，提出采用移动立方体方法 完成腹部器官和脊椎的重建，可解决二维序列影像到三维立体模型的转换问题。最后本文用试验验证了该方法对腹腔内器 官三维重建的有效性。

An important branch of medical image visualization, 3D reconstruction, has always played an important role in the field of clinical medicine and has been a hotspot of computer science and technology field. Starting with three-dimensional images, doctors can determine patient’s lesion morphology, status and location more accurately, thereby improving the accuracy of medical diagnostic techniques. In this paper, the preprocessing and segmentation results of CT images were further studied. On the basis of segmentation of organs of interest in two-dimensional abdominal slices, the method of Marching Cubes was proposed to reconstruct abdominal organs and vertebrae, which could solve the conversion problem of two-dimensional sequence images to three-dimensional model. Finally, this paper validated the effectiveness of this method on the three-dimensional reconstruction of abdominal organs through experience.
