摘　　要：该文研究基于VTK(Visualization Toolkit)进行CT和MRI医学图像序列的三维可视化及任意方向的交互式切割方法。提出新的方法即"三维交互式切割法",对三维立体空间和重建后的三维物体进行切割,以便观察物体内部结构。该方法通过定义隐含的平面来对物体进行切割。实验结果表明:通过所提方法可以对常见医学图像序列和三维重建后的图像进行交互式切割,交互性能好,切割速度快,效果逼真。The aim of this paper is to study the methods of 3D visualization and the 3D interactive clipping of CT/MRI image sequence in arbitrary orientation based on the Visualization Toolkit （VTK）. A new method for 3D CT/MRI reconstructed image clipping is presented, which can clip 3D object and 3D space of medical image sequence to observe the inner structure using 3D widget for manipulating an infinite plane. Experiment results show that the proposed method can implement 3D interactive clipping of medical image effectively and get satisfied results with good quality in short time.
