Study on 3D CT image reconstruction and interactive clipping

It is necessary to incise a 3D object to obtain detail structure information inside in the process of developing 3D medical visualization system. VC++6.0 with VTK toolbox are used to reconstruct 3D images using the CT slice sequence in DICOM format. Cuboids that can be controlled to zoom, move or circumrotate by mouse and used for clipping the object of 3D object. The technique can realize the real time interaction clipping of the reconstruction object.
